5: 2011 Porsche 997 Speedster – $400,000
Seinfeld has begun to collect modern Porsche models as we can see by this entry. The 2011 Porsche 997 Speedster was a limited-production car that was meant to reinvigorate the brand. When Porsche creates a new car, they generally keep the production numbers low, thus creating a rarity with every model. Performance-wise the 2011 Porsche 997 Speedster is about as fast as you can get for this kind of sports car.

The beauty of the exterior is only mirrored by a functional interior, with plenty of trunk space and all the usual Porsche fair. Don’t let yourself be fooled, though, this is a serious performance car that can burn some serious rubber on the track.
