Customer Testimonials



"The first word that comes to mind when I describe Dave to others is perfectionist.  But I don’t have to actually say it, they just look at my car. Over the years Dave has helped me maintain my daily driver, a 1981 Porsche 911 SC Targa, looking good and driving well.  Most recently, I embarked on a ground-up restoration of a 1974 Porsche 914 2.0.  Dave not only did the bodywork and paint (flawless) but helped with setting up the suspension and other difficult fitments. 


Equally as important, Dave was a mentor for me throughout the project; freely lending his experience to problems I encountered along the way.  As busy as Dave is, he ALWAYS has time for his customers, whether it is a walk through the shop to check on your car or via phone consultations."

- DENNIS S. of Green Bay, WI - Porsche 911 and Porsche 914


"Dave is the only paint and body guy I use when it needs to be perfect. I have very high standards and when the car comes back from Dave's shop, I literally don't have to inspect it...I know it's right. This is extremely rare in the industry."

- AARON HATZ of Flat Six, Inc. in Bloomington, MN


"I am writing to express my gratitude for your exemplary work on our classic sports cars.  The fact that you can skillfully care for our various marquees – Porsche, Ferrari, Jaguar, Mercedes, MG, Corvette, etc. is a great comfort to us.  We always know when we entrust a car to your dedicated hands, we get the best possible work and at reasonable prices.  Your advice on our cars is always spot-on.


I am reminded in particular of the great work you did for us to prepare our Ferrari Dino 246 GTS for the FCA International Concours.  Needless to say, we were delighted with your fine services and the invaluable assistance at the competition.  Achieving “Platinum” status for the car, plus winning the “Dino Award” to boot, were extremely satisfying, especially in such stringent and difficult judging. The fact that other noteworthy shops were unable to get the “Platinum” for their cars made that all the more significant."

- DENNIS G. of Green Bay, WI - Ferrari Dino 246 GTS


"I met David Treichel over 2 years ago and my experiences with him have been nothing short of great.  I have purchased three rare cars in the past two years in the Midwest.  Dave gave me an honest evaluation of all three cars and each evaluation was extremely accurate. Once each car was purchased by me, he performed a service and/or restoration on every car. I can't begin to express how satisfied and grateful I am for the work he has done for me. I am looking forward to working with him on future cars. "

- ALEX W. of Los Angeles, CA


"I have worked with David on two project thus far, with a third in the works.Our first project was the conversion of a 1978 Porsche 911SC "short hood" body into a 1972 Porsche 911 ST  "long hood." The project was very complex given the donor car was a sun roofed body. The finished car eliminated the sun roof, reconfigured the front end to accommodate the long hood, add ST flares and bumpers all around, plus install a thru hood gas filler. Finally, we painted the finished body in a high gloss, Porsche silver with body decals.


Our second project is a rotisseried renovation of a numbers matching, 1963 Porsche 356 T-6 Coupe. We are early stage in this project with completion of stripping, dipping, and early stage body work to replace rusted sections.


Dave is a consummate professional (and a heck of nice guy). He treats these projects as if they were his own. His attention to detail and demand for perfection, put him in a unique league of artistry rarely seen. I met Dave through Aaron Hatz of Flat Six, Inc. in Bloomington, MN, who is leading both project builds. Their relationship and collaboration, along with Aaron's confidence and respect for Dave's work, will result in completed cars of significant prominence. I would recommend Dave and his work without taking a breath."

"I first met David in 1993.  His passion for sports cars was apparent from the moment I met him.  He initially did a full repaint of my 1983 911SC.  His attention to detail and quality of work transformed this 911 into a beautiful car.  The clarity and ‘flatness’ of the paint was something I had never saw on other vehicles. 


As the years passed, I approached David to convert this 911 SC into a Turbo look coupe.  David took the time to sit down and listen to what my dream of this vehicle would be.  I turned the car over to him and his creativity and passion turned this 911 SC into one of the most stunning Turbo look 911s.  His talent is beyond painting – his efforts included providing custom sized wheels, massaging the front and rear turbo flares to match the vehicle perfectly, lowering the suspension to provide the aggressive stance and of course the countless hours of paintwork.  He installed fine interior details as well – Seats, steering wheel, shifter, etc to help accentuate the beauty of this one of a kind car.  His work was done to perfection and in a cost effective manner. 


I have had the pleasure of watching David and the transformation of his skills and capabilities over the past 21 years.  He is always striving to challenge himself, but he has never lost sight of how to treat his customers and their dream vehicles."

- TODD M. of Green Bay, WI - 1983 Porsche 911SC and 2007 Porsche 911 GT3 




"I am a very particular customer that demands the best and David’s attention to even the smallest details sets him apart from other automotive restoration centers. I have attached a picture of the latest automotive creation Dave constructed for me. It’s a 1968 Plymouth Barracuda Resto-Mod (restoration with new automotive modifications) with a 426 Hemi engine.




David has also built a 1969 Chevy Camaro Convertible resto-mod that he finished in 2001. He has pictures of this on his Facebook page."

- JOE S. of Appleton, WI - 1968 Plymouth Hemi "Cuda"  and 1969 Camaro SS
