These are the 3D models for both Photoshop and Keyshot or 3DS Max.
I have included the wireframes.....although they aren't of any real use, but have created a sort of mask....that may be a little more useful.
Each folder contains the PS file....and the raw model for Keyshot or 3DS Max.
The 2013 cars will follow later.
