12: 2004 Porsche Carrera GT – $440,000
Another exotic sports car that both Seinfeld and Leno have in common, the Carrera GT often gets a bad rap. The car is notoriously well-designed in the performance aspect, but other areas of the car could use rectification. The low design of the car drags on just about anything, and unless you are on the track all day this makes it impossible to drive. Performance is still at the top of the level and few cars can match the Carrera GT to this day.

Seinfeld, like Leno, has kept his model in pristine original condition, after all, maintenance on these things is so expensive who wants to risk it. The 2004 Porsche Carrera GT was a truly groundbreaking car in every sense of the word, and few exotic cars have come close to matching the performance.
