2009 Nissan GT-R Coupe Premium 2dr Coupe AWD (3.8L 6cyl Turbo 6AM)
Only the transmission
 Had the car for 5 months now with 11000 km.  Transmission started to make severe mechanical noise, couldn't shift from 1st to 2nd.  The dealer transplanted a new transmission... I still love the car, enjoy the acceleration and cornering. If not for the transmission, it's a reliable car on every aspect.  When you can beat Porsche Turbo at about 1/3 the price, I couldn't complain.
