We've all got a bit hard-on for the McLaren MP4-12C, and the idea of a GT3-spec MP4-12C race car, while obnoxious as all hell to type, is amazing. McLaren has updated the car's aerodynamics, ECU, electrical system, cooling via a new hood and duct system, and suspension. The engineers say that this will allow the car to operate at high temperatures for longer periods of time, and reduce tire wear as well. 

Less pit stops mean more wins, and the 2012 MP4-12C GT3 managed 19 outright wins out of 98 events last year, so this should be good. To top it all off, it only costs $515,580.
