I modeled this in CAD Rhino, everything is extremely detailed, both the exterior both the interior.
The first 2 renders courtesy by Germano Vieira.
Materials/textures not assigned/applied in the Rhino file so the renders you see are just as example and dimostration of what you can do with this car using the provided .bip file, where everything is ready to be rendered apart from some textures which are provided anyway in the attached texture pack. Basically, you just need Keyshot to use the .bip file.
You'll get the geometry only, but everything is layered so that it's very easy to render it.
Don't worry about the polycount since Keyshot or V-Red or V-Ray easily will handle that amount.
