The Mercedes-Benz SLR McLaren was unchanged in the 2006 model year, its second year of production. And it stands to reason - the car, built as a joint venture between DaimlerChrysler and McLaren auto group, seemed perfect in 2005.
Only 500 of the two-seaters are made in each model year, translating into a price tag that flirts with half a million dollars. A 5.4 liter, V8 engine lends the car an astonishing 617 horses.
The SLR McLaren also makes unique uses of materials. Rather than being built from cast iron and sheet metal, the cars components are crafted from carbon fiber composite.
