Mercedes-Benz SLR McLaren Roadster 722 S

Want. With 650 hp and a top speed of 220 mph, the Mercedes-Benz SLR McLaren Roadster 722 S ($TBA; Jan. 2009) may quite possibly be the fastest open-top production car ever built. Powered by a supercharged 5.5 liter V8 engine hand-built in the Mercedes-AMG engine shop in Affalterbach, the 722 S features a carbon fiber body, crystal antimony grey paint finish, and a soft top that can withstand sustained 200 mph+ top speeds. Only 150 of these very-much-not-for-mass-production rides will be sold. [via]
