Are you after full-physics stuff that allows airborne cars or cars that just stick to the ground?
I have an older demo that you may be interested in that uses no outside physics engine, but also I have some ODE and Tokamak stuff that allows for a more realistic bouncy car, but achieving decent handling is harder.
