[Implemented] GT3 CLASS

[[RDSR] Speed Demon]

My request was clear and unambiguous. It had to be all in one package (like in F1)
If they all perform the same, why do you make them all buy them separately? If I wanted to do that, I would open a post for each one. Nobody is going to pay 125 thousand euros for a car you can only use on the track. But if you give 5 more cars with it, you encourage people to spend money.
