Absolutely nada. But I just like to point stuff like that out to the guys who want to 'Keep NASCAR American' and boot Toyota, without even realizing the Toyota (production model) is the only American built car in the field. As for the stock cars themselves? They're all American built, and as I said earlier, if other foreign automakers want in to NASCAR I'm all for it! It'll create jobs here, and it might add a little (but not much) variety to the NASCAR field. NASCAR stokers are ALL American cars... even the Toyotas!
The modern stock cars, be it a Ford,Dodge, Chevy, or Toyota, are all built by guys named Bubba and Jake,- right here in the good old USA. To me at least, the origin of the company the car is supposed to represent is pretty much irrelevant. I just think some people read too much into the 'brand' thing.
