Thanks Middle :)
It would require about 300-400 hours on my part for modeling and for the "flight model".
Someone would need to do the panel, gauges, sounds, and textures of course.
Mapping for textures would be a bit more complicated than the straight planar mapping that I do.
You should check some of the 3D sites that have a lot of these vehicles already done.
Check out this truck at Turbosquid: http://www.turbosquid.com/FullPrevie....cfm/ID/539174
The pickup is much more complicated to model than this sheet metal'ed stock car so it would be a fair sized project.
The handling would need to be different as well, probably more like the cars that are available for FSim.
