Everything went perfect!

Mark, everything went perfect. Bernie is a great mechanic. A great pilot. But more important than that, a great person. I am very happy that you suggested a guy like him to do the job. Thanks for that also. The airplane is perfect. As expected. And I am very happy.




Thank you again

Mark, Darcy and Kathi,
Thank you all for another terrific job of Marketing, Sales skill and Closing.
Much respect
Thank you

Thank you!

Thanks again for your efforts in the Duke sale/purchase. It was a pleasure to work with you. Cheers!  Clyde 


Thank you!

I knew of the reputation of Mark Clark and Courtesy Aircraft as the premier aircraft broker in the industry.
When it came time to sell our SNJ/AT-6, the first person I called was Mark Clark. He promptly returned my call and walked me through the process of what was expected to sell the airplane.  He took the time and thoroughly reviewed the logs and other documents of the airplane before letting me know what sales price to expect.  He was very objective about the pluses and minuses of the airplane and priced it accordingly.  Mark’s knowledge of the market and experience in advertising along with knowing how to work with potential buyers was invaluable.  He coordinated the visits and pre-buy by the buyer, which made my schedule easy.  Most appreciated was his prompt responses to questions and keeping me up to date on the progress of the sale.
Not only did he sell our aircraft in a timely manner and got us a generous closing price, it was a pleasure to work with a fair, forthright, and knowledgeable professional. I highly recommend Mark Clark and Courtesy Aircraft as the first and only agent you’ll need to buy or sell an aircraft.

Sincerely, Richard

Thank you for your great work that you did as a team on my behalf!

Please forgive the fact that it has been nearly four weeks since I departed Rockford in N128BC. The last two months have been a whirlwind between two duty roster periods, annual simulator training, and a trip to Illinois. As you can imagine, despite being at home for three of those days, there was little time to relax.

I want to express my most sincere gratitude and appreciation to everyone addressed in this email. It was a schedule that started with my first phone call with Mark Clark (June 22), signed Purchase Agreement (June 24) to completing the Practical Exam with Ed Finnegan (November 13).  I have had the pleasure of working with an incredible Illinois Team who accommodated several schedule changes, patiently answered the questions of an excited new owner, and worked tirelessly to take care of all the details.

Thank you for your great work that you did as a team on my behalf. Each of you had my absolute trust from the beginning and delivered without fail in the end.  I had the easiest job of all: show up and receive a fantastic aircraft!  Sales paperwork, ferry permits, LOAs, addressing EVERYTHING that needed just a little more maintenance attention, flight training, practical exam… the list is quite endless.
You all have earned my greatest praise and I am pleased to recommend you to anyone just getting started. I look forward to seeing all of you again in the future, the community is small and you represent the very best!

Thank you,

I will never say thank you enough!

I will never say thank you enough to you for make this happen for me during Covid19 ! Please stay safe and merry Christmas to you!  -Francois

Thank You!

” Mark, I appreciate your handling the sale of N5632F so cleanly with no complications.  Thank you!  Have a great New Year.”

Fantastic service from the entire staff. As someone that is new in the aircraft and warbird ownership arena, your attention to detail and ability to dissipate any apprehensions with plain language answers and facts on ownership sealed the deal. I strongly recommend Courtesy for any warbird requirements, sales, service or administrative support. You guys are the best.

Posted By: Keith Masserang

The experience was a positive one. Considering that there is always a little contention when negotiating, things worked well and the airplane has been trouble free in the first 4 months of ownership.

I probably bought the cheapest plane Mark sold in 2011, yet he treated me like I was buying a Corsair! The transaction went flawlessly even though it was not in Mark’s inventory. I very much appreciate the efforts of your company. All the best.

Mark, thanks to you and your team for moving our T-6 in a timely and professional manner. I’m sorry it needed all the attention you had to give it, but glad it was in your capable hands.

Mark and Kathi, thank you for this good news, nice job. I have one more reason to be happy to have worked with Courtesy for buying a Mustang. Thanks again, I appreciate the way you work.

My thanks to Darcy and Courtesy for helping make purchasing my second plane such a trouble free event.

Posted By: Mark Holt

Everyone was very helpful in the purchasing process of my L-19 Bird Dog. I was very pleased with the professional manner in which this transaction occurred.

Darcy, Made it back to NJ after about 5 hours of flying. N95242 is a wonderful plane and was a joy to fly this afternoon. I wanted to take a moment to thank you and Courtesy for your professional handling and attention to detail. It was a pleasure doing business with you. Have a wonderful holiday season!

Dear Mark,

I just wanted to drop a note and say thanks again for the support provided by Darcy and your entire staff concerning the sale of my Piper Lance aircraft. This is the second aircraft that you’ve sold for me – and I think this one went even smoother than the first.

Everyone on your team knows what they are doing, appreciates a sense of urgency and possesses a pragmatism that is refreshing and necessary in today’s difficult aircraft marketplace.

Thanks again to all of your team, and I assure you that Courtesy Aircraft will remain my Number One resource in the aircraft acquisition/marketing arena.

Hello Mark, Sorry for my late reaction but I did spend four days in the Mustang. I am very happy she has arrived and we worked hard to assemble her. She is in marvelous condition and built with enormous craftsmanship. We all are impressed about the rebuilding job that has been done. We had to trust you about the aircraft and it was worth it, we only had some internet photo’s to decide the sale. We got a wonderful restored Mustang from you. Thanks Mark.

Posted By: Marcel Peerlkamp

Scat VII is now operational. Last Friday I did two test flights. They went very smooth. Saturday I flew with Jan for the first time. We went on a 2 hour navigation flight and ferried Scat VII to Antwerp in Belgium. Jan was very impressed by the performance of the Mustang. He is very happy to finally have flown his new aircraft!

Thanks for all your support; it would never have been possible to buy a Mustang of this quality, without inspecting it ourselves first, if Courtesy wasn’t the broker. Well done to you and your team!!

Mark, I wish you and your team a Merry Christmas and a happy 2010!

Posted By: Robin C. Crandall, M.D.

I write this letter to personally thank you for your kind donation to help bring the Hawker Sea Fury “Sawbones” to Reno and back this year. Without your support this type of racing activity would virtually be impossible. The airplane arrived in Reno safely and cam back with very little problem. We did have a few coils that had to be replaced and some ignition parts on the way back from Reno but otherwise we got back safe and sound…..Thanks again for your tremendous support of this racing team.

I have been an active viewer of this website since my first flight in a CJ6A Nanchang back in 1998, and my hopes of one day becoming a Warbird owner/operator had begun. It got me addicted to flying, and to Courtesy’s Website! 10 Years later, I am currently flying Learjets. Throughout my last few days of high school, and throughout college, Courtesy Aircraft was always a site that I could get my warbird fix. It’s amazing to see all the different aircraft come and go – and even watch the same ones pop up more than once! I remember about 10 years ago when I was just finishing up high school in the Bay Area, and Ray Diekman was at the Santa Rosa Air Show with Marines Dream. David Etchell, a friend of Ray’s, was the man who took me on my first flight the year prior in the Nanchang. At the time, I didn’t know anything about Ray’s amazing Corsair. I remember he was not flying it in the airshow that day because he was feeling sick with a head cold, but he offered me to climb up inside… it was just freshly restored and what an amazing treat that was. I remember asking him how fast he had gone so far. He replied with “Around 350mph.” Years later I see it for sale on Courtesy. It brings back such great memories and only now, years later, I realize how special that was. Such a small community the warbird family is, and one day hope to be an owner and part of. One thing’s for sure, when the day comes along where I can start off with a T-6 or T-28, Mark Clark and the people at Courtesy Aircraft will be the folks I seek.

I bought ’57 BE35H from you two years ago. Great airplane. Hangared since I got it. Virtually unchanged, good compression, using 0 oil, no metal. Looking to trade up to faster BE35 or light twin (Baron, PA-30, Aztec)…Contacting you because 1) You know my airplane, and 2) You delivered exactly what you said you would.

Posted By: Milt Concannon

I really appreciate the hospitality from Courtesy Aircraft and Heritage Aero this last few days when I picked up my T-28. I cannot thank you all enough. Mark Pasqualino is an absolutely terrific flight instructor and with a little more help from him I am sure the check ride will go smoothly.

After a late start yesterday, we made it to McComb after dark without incident. Plane ran and performed well and was realitively oil free this a.m. Went out at 8:00 a.m. this morning to put the plane in the hangar and there was a crowd of about 30 people slobbering all over the plane. (our airport doesn’t see 30 people in a week!)

I just want to thank you for the smooth transition on the purchase of my first twin Baron E55. I love the aircraft and I am having a good time flying it. Your staff was very friendly and I can’t wait until the next purchase of my first warbird. Have a great year I will update you when I fly my E55 to the destination that I want.

Posted By: Bud Walker ATP-756232

After 70 years of flying 160 different civil and military airplanes and being recognized (at age 83) as being the ‘oldest active airshow performer in the USA’. I busted my FAA medical and got grounded – sold my Pitts S1C on 8 Jan 09 and have almost stopped whining. I thank you for the E-News. Along with my civilian experience, I flew as a USMC aviator, the N2S, SNJs, FM-2, F6F-5, F8F-1,-2, F4U-4, -5, TBM-3, TO-1, F2H-2, F9F-2,-5 amongst many others and loved them all. So now, in my non-flying years, I find solace by getting a warbird fix with your E-News and looking over your the inventory on your website – which has really helped me reconcile my situation! I wish the Courtesy Aircraft crew a happy, healthy and prosperous 2009 and my hopes that you’ll always have a Grumman Bearcat (my all-time favorite – the Pitts Special of the prop fighters!) in inventory for me to drool over.

Posted By: Steve

Mark, You might like to know that I have had a very good year with the ’66 V-35. I flew 60 hours last year and it has proven to be exactly as you represented it to be.

Posted By: Morris Gardner

I can’t thank you enough for a smooth, no sweat transaction…not to mention that you “pulled a rabbit out of a hat” by selling my Super Decathlon as the economies of the world are seemingly drowning in an economic climate that might eventually prove to be even more disastrous than that experienced in the immediate aftermath of 9/11/01, when you sold my Stearman!

Furthermore, you and your staff are to be commended for putting just as much effort and enthusiasm into these transactions as you do with the rest of the planes you handle, most of which represent sales involving ten to twenty times the market value of these birds.

Best regards and thank you once again!

Posted By: Paul & Lisa Walter

The T-37 arrived and created quite a stir at the Waukesha, WI airport! It could never have happened without your help in guiding us through the purchase and T37 rating. Wife Lisa approves; now I have to figure out how to get her out of the left seat!

Posted By: Tom Duffy

All was great, Terry Rush and I went for a type ride in Texas in the MkIX Spitfire. Once again an aircraft purchased through you was exactly as represented. This is the third aircraft I have purchased through you and I have never been disappointed. I believe no one has the knowledge or experience of the warbird market that you have. I know that you always have all the facts and avoid puffing. You ahve made this a fun and painless experience as usual. You and your staff are the best.

Posted By: Bob Resling

I appreciate the effort you put into selling the old bird. I would not think of buying or selling an aircraft without using the services of Courtesy Aircraft. I have now bought two and sold one through you and I have been extremely pleased. Your reputation in the industry is well deserved.

Thanks again

Posted By: Brett Zachary

Dear Mark and everyone at Courtesy Aircraft,

I wanted to write and thank you for assisting me in the sale of my T-6. I listed the aircraft with Mark on a Thursday and I was pleasantly shocked when he had a buyer and a deposit my Monday afternoon!

The process of getting the aircraft to Rockford along with the pre-purchase inspection, attending to some minor maintenance and the documentation for closing was as seamless and painless as I have ever experienced. If only selling my Pitts on my own had been so easy!

When I’m ready for the next Warbird, Courtesy will be my first call.

Best Regards

I was on the web yesterday looking at your aircraft for sale and was intrigued by this P-51. I am originally from Winnipeg and the fact that this is a former 402 City of Winnipeg Squadron Mustang was of great interest. My father was a former C.O. of 402 Squadron and flew Vampires and Mustangs in the reserves post war after 2 tours during WWII as a Lancaster pilot and Mosquito pilot in the RCAF. In fact, I went to his log books and on two occasions are entries from 1951 where he flew this particular Mustang, aircraft no. 9563. Quite amazing that I can look at those pictures and know that this is the particular aircraft that the old man flew. Unfortunately, I am not a Microsoft millionaire or I would be quite tempted to acquire this airplane. Thanks for posting these pictures. I found them to be of great interest.
Good luck to you.

Hello Mark,
I wanted to thank you for making the purchase of my Beech E-55 such an easy and enjoyable experience. I especially appreciate you taking care of the negotiations for me as I do not do well at that sort of thing and always felt in good hands throughout the process. I don’t think that the excitement of owning an airplane has actually sunk in yet!

Thank you again

I still enjoy seeing the listings on your website. The last brochure I received from you all had my beautiful P51 on the cover, and yes it was me flying SU SU. What a beautiful P51. Thanks for the kind words on your website saluting veterans this Veterans Day Weekend. I have been on active duty recall to the Navy since April and I have just been extended for another year. At the present time I am not assigned in Iraq. I am working for a Rear Admiral in Jacksonville, FL on his staff as Region Air Operations for what is known as Navy Region Southeast. Our region encompasses all Navy Installations from Florida to Texas – up to North Carolina. The Airfields I work with number: 12 primary and 19 outer lying fields (OLF’s). I am very proud to be in this position as a Navy Officer, especially when times are tough for our Country. I dream of the day I may get my SU SU back, but I am very thankful to have the keys to a friend’s Texan to fly!

Take care and have a safe holiday.

A very good idea, keeps us informed concerning the latest aircraft available. Well, organized and thought out. Thanks for including me.

We are very pleased to let you know that we made it safely to Germany. We would like to take the opportunity to thank you and your team for the superb work, once again, I must add, you did with regard to the market research, purchase and mods of the Cessna 182Q. We appreciated very much your professional service, smooth handling of the transaction and full support at all times.

Furthermore, we thank you for your recommending to us Cliff’s workshop, Heritage Aero, which did an excellent job. We are fully satisfied with the our new aircraft, it flies great, no problems whatsoever with the engine. We learned that it can easily handle extreme weather and flight conditions in parts of the world that we normally do not get to so often.

We may add that David and Tony at Avionics Place also completed their works, timely as agreed upon. Once again our appreciation and thanks for the brilliant work you did!

Owning and flying a Mustang has been a life long dream. My father crewed P-51’s in Korea and with the Kentucky Air National Guard. Some of my earliest memories are of him and this airplane. You have made this dream a reality. Your expertise and advice have proven invaluable. The folks you network with such as Wally Zook in financing and Tony Rukavina in insurance were great to deal with. This entire transaction has been a delightful experience. I will certainly recommend Courtesy
Aircraft to anyone interested in joining the Warbird community, and plan to use you again if and when I am fortunate enough to acquire my next dream … a North American F-86!

Hi Mark,
Many thanks or the professional way you handled the sale of the TBM for me. By now Larry Ricker (pilot shown here ready to deliver TBM) should be in Oakland. Thanks again to you and your crew!

Posted By: Bo Ewald

Just a little note to let you know that Mark P. and the T-34 arrived in great shape on Sunday afternoon. Thanks for all of the help – really appreciate it. You did a great job representing the aircraft (and Courtesy), and helping juggle everything so that we could get it inspected, pre-inspected, annualed, paid for and delivered.
Thanks again – it was a pleasure doing business with you!!!

I hope this email finds you doing well. I just completed my first 100 hours in my T6-G, purchased through you in April. This plane is about the best thing I have ever bought and I enjoy it tremendously. I completed the wing AD without problems or findings and was one of the first 10 planes back up in the air. The annual went eventless and the plane is performing well. I modified it with a high roll rate kit, which I highly recommend. For those worried about fuel cost, I have been able to fly the plane averaging 24 Gal per hour, with the average flight being 1 hour – well that still puts 2,400 Gal through the tank, but it is just too much fun!

Posted By: Jens Meyerhoff


I just wanted to drop you a quick note that we landed safely last night at 6:00pm at LVK. The plane performed flawlessly and consumed only 27gal of fuel per hour. Total flight time was 14.0 hours for the 2,000 miles. After we left Rockford we flew to Grand Island, NE for our first night stop. Unfortunately we got stranded there for the next day as severe thunderstorms and hail came down from the Rocky’s. However, we got out of there on Wednesday morning and just flew home via Laramie, Salt Lake, Reno into Livermore. It was a long tour but we had great weather. Today we have rain and a low ceiling, I am glad we got here yesterday.

Thanks again for all your help. BTW, we only used 1.5 Gal of oil!

Dear Mark,

It’s been a pleasure doing business with you. Your warmth and professionalism in helping with the purchase of my SNJ-4 has been exceptional. You head up a first class operation.

Buying an airplane is always an important move, and buying an “exotic” aircraft can up the stress level a lot. When I bought my Focke-Wulf 149D from Courtesy Aircraft, I found out that they took their name seriously. John Kraman and the entire staff could not have been more patient, courteous and most importantly, knowledgeable. They took all the time I needed, directed me to the appropriate shops for the work that I wanted done, provided all the documents that make owning this aircraft as stress free as if I was buying a conventional flying machine. I was never pressured and I had that warm and fuzzy feeling that one gets when you know this important transaction is being handled by people who know their business and make sure that you know all the pertinent information to make flying a pleasure. I have owned seven aircraft, purchased from seven different sources, but this time, it was a delight.

I wanted to drop you a note and let you know how much I appreciate your handling of the sale of the L19 to me. This is the fourth airplane that I have purchased from you but the first that I have ever “purchased, site unseen”. The digital pictures that you emailed me made it easy for me to make the buying decision. They were very detailed and showed the exact condition. Having worked with you in the past, I knew that I could trust your grading system on describing the condition of the L19. Much to my benefit, the airplane was actually nicer than your description. This is always a pleasant surprise. Thank you for arranging delivery, that made the transaction a “No bother” to me. Your pilot was very professional and pleasant to meet. I am in the sales business myself and I just wanted to say how much I appreciate your honesty and professionalism. I look forward to our future dealings.
