Do you use simulation tires? Crude, but I used GT3 to demonstrate how mid-engined cars rotate differently than front-engined rear driver cars. They've made the Ruf 3400S much easier to drive at the limit.
I currently have four 190's and two of the motorsport cars in my "garage" in the different colors I am contemplating. Has anybody played the new "Project Gotham Racing" (I think that's the game) for X-box? On the commercial it has a red S2 (Looks like) getting chased by a cop car.
