A Lifetime of Involvement in the Automotive Industry

Participating in historic racing events, rallies, and concours, and with 35 years in the trade, we have gained the experience to give our clients good advice in many areas of the car collector hobby. Historic car racing, rallies, and concours are sports that are growing with events across the USA and Europe. These events are an opportunity for passionate collectors to enjoy using their cars as the original designers intended, in competition. As both an entrant and judge in Concours d’Elegance we understand the collector’s love affair with sharing these beautiful cars with others.

In the  small historic racing and sports car community, Grand Prix Classics is a trusted, leading authority in car values and market direction. We understand what makes a car collectible and what gives it value. Our years of experience have given us the credibility to contribute to automotive price guides in the Sports Car Market and the Vintage Race Car Journal.  Even USA Today and Forbes Magazine quoted Grand Prix Classics’ opinions on the investment of collecting cars. We have written formal appraisals for finance and insurance purposes and have been called upon as an expert witness in complicated automotive cases.  

Our business and the specialty cars we sell have been featured in a variety of automotive publications including: Automobile Quarterly, Autoweek, Excellence, F1 Racing, Porsche Panorama, Sports Car International, Motorsport, Victory Lane and Vintage Motorsport. Mark  appeared as a historian on the DVD re-release of the 1966 film Grand Prix. We are privileged to be a guest speaker for many automobile clubs as well as hosting clubs at our business.
