Jerry Seinfeld | 1973 Porsche 911 Carrera RSR IROC |  $2.31 million

While studying for his degree in communications and theater, Jerry Seinfeld developed a passion for comedy. This eventually led him to perform in more than a few stand-up comedy and open-mic gigs after graduating from college. After some time, Jerry made his way to the entertainment industry, where he has since become most known for his now-famous show Seinfeld.

The actor-comedian-writer also worked on projects such as The Marriage Ref, the Bee Movie, and Comedians in Cars Getting Coffee. While he’s undoubtedly got a knack for making audiences burst into laughter, Jerry is also quite fond of collecting cars, especially Porsches. Along the way, though, he opted to auction off 17 of his four-wheeled wonders, seven of which were Porsches. Among them is his 1973 Porsche 911 Carrera RSR IROC. While it was initially estimated to be worth between $1.2 to 1.5 million, the 911 Carrera was sold for an even higher price of $2.31 million.
