Here is a picture of a pre-production Bonneville GXP

I was wondering about the wheels/sizes.
Thanks for the reply
I don't know GXP, but I do know pre-production vehicles at GM. I work on them all the time. I suspect it will be difficult to answer your question since there are about 12 (sometimes more) levels of pre-production vehicles. The first the public gets to see are the concept cars, but once a car moves into development for production and gets beyond the clay model stages (where body lines, features, and part break ups are finalized) there are cubing fixtures, body bucks, prototype, pre-production builds, match event builds, non-salable, and salable, just to name a few. Some of the earlier vehicles are produced at the Build Center in Warren Michigan, some are produced off-line at the assembly plant, and the final 2 or 3 levels are produced in limited runs on the assembly line. New vehicles are not deemed ready for distribution until after salable builds and the vehicles are approved for "ship to commerce".
All of which is a very long way to say "pre-production" can mean a variety of vehicle levels. Are you referring to your vehicle? Do you have reason to believe you have a pre-production vehicle? Any vehicle licensed and on the road would have to be from salable builds, since anything prior to that level cannot be legally driven and are supposed to be crushed. Salable build vehicles are supposed to be production representative in every way, and are the vehicles GM uses to get internal and external approvals necessary to move into production. Therefore, if there is a pre-production vehicle on the road, it should be the same as a production vehicle.
Why are you asking?
