That's just adjusting the wheelbase and COG positions and it'll sort the wheels out.Thanks for the info, I actually had some errant keyframes for some odd reason that kept hijacking the position of the car. As for the glass, turns out there was actually 3 different "glass" materials used in the model and the one I couldn't find happened to be the culprit.
After fixing all of that I obtained a much better result but the scale of the actual vehicle is still off unfortunately.

Oh well, looks like that's a problem for tomorrow...
And yes keyframes would have messed you around a lot in Blender. Always important to make sure you have that set right.
