Well, I'm definitely stocking up on Mopar shirts then.
Personally, I'm not concerned about getting performance parts, as my Challenger will be put into daily service immediately and I have few opportunities to race between work, home and back.
Since it's likely that the Challenger will be the last new car I ever buy, I AM concerned, about eventual replacement of conventional components -- things like the flat door handles now appearing on the test cars, which if the 1970 model serves as a guide, will break after 10 or 12 years. Frankly, I could care less if the box the part comes in is stamped Mopar or Made in Outer Mongolia, as long as I can get the stuff I need.
For performance fans, though, this indeed could pose a problem.
