The "Mustang" and "Challenger" are like that too LownSlow the nose and tail kinda, sorta look like the production car while the middle looks...well...............not so much like any of the production cars the race cars are named after right now.
Well, make the chassis one specific set of tools and the body and engine tools separate but 100% compatable with the chassis tool. Then either provide the approriate decals for the car in question and offer just a plain, decal-less kit (like theLinberg cop car kits) for those that want a driver they havent licensed just yet.
