Add A Test-Drive Option On Dealership

I also don't really like that idea because of the reasons above. A stock car can't tell you if the car is good when it's tuned, especially not since the dyno tuning update.
A solution would be to have the car tuned on 2/2/2 when testing, but still it's not a good result that you can trust, because dyno has still a big effect on the handling as well.
