I did 5 or 6 hours yesterday and 12 hours today and the UVW unwrapping is complete (lets hope)
With that done now, I can render ambient occlusion for each texture so I can start building layers in photoshop and rendering out diffuse colour, specular and some textures will have normal maps (bump)

Here is the UV template for the main body texture, this will be available for everyone to modify.
There are 8 textures altogether.

Main body
Chassis
Cockpit
Windows
Suspension
Tyre
Wheel
Brake Disk
