Estimated Value: $45,000

The Karmann Ghia was Volkswagen trying to capitalize further on people's love for the bug. Seinfeld showed off his Karmann Ghia in season one episode of CCGC with Joel Hodgson. As he tells us, it comes with a four-cylinder Porsche 912 engine. That addition means it'll fetch more than the average value for a '63 Karmann Ghia.
