As an engineer, I find the rep's statement a little questionable.. $200,000? Maybe he assumes it's a prototype vehicle, which I would think that figure might be low, but I wouldn't think that a prototype vehicle would be taken to dealerships except perhaps locally in the metro Detroit area.. By now any vehicles being shown should be "saleable" vehicles, even if they are vehicles slow-built on the home-line prior to start of regular production. As such they might be a little more costly in terms of labor, but components should be at production pricing. I could be wrong, I never got involved with pricing between the OEM and tier 1's.
What I do know is that among the uses for these saleable pre-production vehicles, it's common practice that they might have testing or show uses, and at the end of this usage they do get sold and normally company employees are eligble to buy these vehicles - and it's not for $200,00. But of course, those employees buying these vehicles don't want them trashed or the OEM doesn't want to have to repair trashedness of the vehicle.
