What if GM made a car for 60% the price of an M3, but it had an M3 engine, brakes, suspension, chassis and everything that makes it perform the same but the difference was the exterior appearance and maybe it was less stylish, but performance wise it was identical as were the mechanicals that made it up?
How many people would buy the actual BMW M3 over the other one? I'd say not that many.
No actually the more I think about it the more it doesn't seem true for the poeple in the market for a car like that don't consider GM because BMW is a very well known name for quality and performace. GM isn't so they will still buy the Beamer.
On the second note how come GM has BMW parts anyways?
