I'm looking for car models that have the "mechanical's" (suspensions, drive train, engine, etc) not just the body and wheels. The models can be in CAD or poly format. Does anyone have any good resources for models like this?
Not very sure where you can find all of these, but look through this link if there's anything useful. however, the more precise and detailed the designs are, you might need to pay for the models.

All models on GrabCAD are free, but very few go into that amount of detail. If you don't mind experimenting with trucks/lorries lind of models then this is one of the best on GC - https://grabcad.com/library/tamiya-king-hauler-truck-complete-1
