1: A dedicated rallycar with 4WD, maybe two. One from the 80's and one from present day.
2: A supercar, something like Koenigsegg, McLaren F1, Bugatti, you get the idea.
3: An expensive family car, Audi RS6 for example.
4: One open wheeler (think LFS got enough soon), either an old Formula one car from the 70's, or one big motha phunka drag racer.
