Black always black like my real cars. Most cars tend to look good in black. IMO
So here is a new twist to this question, If you could pick just one kind of aftermarket body shop, would it be : A) a new skin design like in GT2 B) a bigger variety of colors C) a shop that you could design your own design
The reason I pick the colour I do for my cars, is because I feel that the colour suits the car.
