6. Porsche 911 Carrera RSR 3.0 IROC ($2.3 million)
This Porsche 911 Carrera RSR 3.0 IROC takes you back to Jerry Seinfeld’s auction a few months ago. Even though Seinfeld said he sold these babies not for money, I am sure he was smiling as this car fetched a $2,310,000 bid.
After the new race regulation put the race-winning Porsche 917 into the blacklist, the manufacturer had to come up with another plan. Thus, this Porsche 911-based race car was born.
At the start of 1974 season, Porsche introduced this new model. Compared to the regular Porsche 911, this one features wider wheel arches, wider front spoiler, and the hallmark rear wing. If you ever wondered why people modify their cars by adding those whale-tail wings, this is where it all began.
Each of these race-winning cars is equipped with 3.0-liter 2-cylinder SOHC engine with a power output of 330 hp. If Seinfeld owned it, it must be one of the best.
