Costing a cool half a million US dollars, in the USA, the SLR Roadster is more than just about a car, it is about a lifestyle only a few can afford! It is certainly a slick looking car, and has plenty of power thanks to the AMG's 5.5 L supercharged V8 SOHC yielding 617 hp. Mercedes claims a 0-to-60 time of 3.8 seconds and a top speed of 206 mph. Plenty fast for a car that tips the scales over 4050 lbs.
