The best sim for me.

I guess my fastest car is Formula Gran Turismo or Red Bull X1.

My favorite car is Toyota Minolta.

My most used car (for almost everything in A-Spec) is Toyota Minolta.

how do you unlock those cars?

im level 26 (a-spec), level 2( b-spec) but im not to good. i win most of my races by having a better car, or using the other cars a sort of battering rams on turns.

also would you be willing to trade any of those cars so i can use them for a while, i will trade them back (youre able to do that right, give them back?)
