As part of its 60th Anniversary celebration, Porsche is trying to find the oldest example of its cars in the USA.

The oldest Porsches and their owners will receive special recognition and become eligible for additional awards, including an exclusive badge from the Porsche Museum in Stuttgart.

Also, Porsche will run a competition for the best presented examples and the winners will get a full model shoot for their cars. The company says it "may" select one car to sit on its stand, alongside the newest models, at the Los Angeles Auto Show later this year.

But the cars don't have to be old to be the oldest.

My Classic Porsche Search is open to all owners who think they have a shot at earning the “oldest” designation for their car. Entries can be submitted for 12 model ranges, including the Porsche 356, 911, 912, 914, 924, 928, 944, 968, Boxster, Cayenne, Carrera GT and Cayman.

In addition, the search is on for the "Grossvater" of all Porsches on American soil, the oldest Porsche ever sold in the United States.
