If you want to mess around with physics, Unity and PlayMaker, by all mean, I will be happy to help you, and I am sure some descent results can be achieved, but I would personnaly invest in Edy's vehicle physics or Unit圜ar if you feel like spending

I would strongly recommend you get a ready made car physics framework from the asset store. Well, you'll likely have to go way further then simply adding a rigidbody setting up a realistic car simulation is tuff, very tuff.
