How to make a car that behaves the same way as a car in Grip?

I am trying to make a game similar to Rollcage and Grip. My only problem is that I cannot figure out how to make the car. I want to be able to drive it on both sides (upside down or regular) and I want it to have shocks like a real car. If anyone knows how to do it, or knows of tutorials about it, or has a file I could download, I would really appreciate it.

I think only grip makers can answer this question.

your only problem is the only problem to make something like grip :)))))

yes I know a guy who has done complex tutos,look:

good luck
