2007 Audi RS 4 quattro 4dr Sedan AWD (4.2L 8cyl 6M)
I would have to say that this car is the most practical performance saloon on the market today. The amount of power you get from that 4.2litre V8 is astonishing. The handling far surpasses anything else in this range. Audis of old used to be really nose heavy and the understeer alot, but with this one you really have the confidence to shove it into the bends. I think this car is better than an M3.
