Ford AU Falcon XR8 Race Car. Massive power, massive torque, handles like a dream.
The only problem is that it spins out on the Karrousel on the Nurburgring.
The Motorsport Elise is a brilliant car as well although its tyres spin, quite a bit actually, but I kept a constant distance in front of a Minolta on Nurburgring, right up until we hit the straight and it flew past me.
Many favs but I will say Mercedes CLK GTR, Peugeot 905 and Sauber C9 for race cars and BMW M3 GTR, Honda S800 RSC and Honda NSX-R LM Prototype road car for touring.
