For some reason I really love the Lexus IS-F...stock. Makes a good noise, pushes if you come in too hot, over steers if you abuse the pedal on the right, and the gearing is really well spaced.
The car I always laugh at is that Sport Wagon R RR. There's nothing sporty about it, it's not a wagon, and it's not a race or homoligation special no matter how many Rs are in its title. It has the performance of a shopping trolley, it's just missing a wobbly wheel.
