Porsche has launched a search to find the oldest Porsches in the nation, to celebrate the 60th anniversary of its arrival in America. Porsche wants to identify the oldest Porsches in 12 model categories, from the 356 to the newest generation of Boxsters and Caymans. The final decisions will get a special badge and inclusion on the Porsche’s 60th anniversary website. The oldest U.S.-market cars from each of 12 models could be photographed and included in the American exhibit that opens October 12 at the Museum in Stuttgart and perhaps the chance that one car will be chosen to share the Porsche display at this year’s Los Angeles Auto Show. Entries will be accepted from now through October 1, and complete contest guidelines are at the website. Best of luck!
