Where to get faithful car/truck models

Not a Solidworks question per se.

I need to model a part on a 2015 vehicle and need to find a supplier of 3D cad models for current year cars. There are plenty of models out there but I can't determine how accurate they are to the actual vehicle.

Does anybody know where to get accurate cad models of the body skin of current year cars/trucks?
