Porsche's Latest Customer Racing Car: the 2011 911 GT3 RSR

Were you wondering what the world's most successful sports racing car was? We'll give you a hint: you're looking at it right now. And you can buy one yourself.

It's called the Porsche 911 GT3 RSR, it packs 455 horsepower (five more than the model it replaces) and it's strictly for use on racing circuits. Which is just as well, because it doesn't look like that suspension wouldn't take too well to pot holes. But if you're looking for a real thrill ride to take around your favorite tracks, this is it. And for 2011, Porsche has updated it with a series of revisions aimed at keeping it at the front of the pack. All it'll cost you is 410,000 euros.
