Wow, this has been a really enlightening experience.
I went from "hey, this isn't a bad price for this car" to, "woa, it's most likely a performance center car, omg gtfo!"
I've now been doing research on the performance center cars and it's split pretty much 50/50 (as with everything else like DCT and moonroofs). I guess I'll just take this like any other car purchase, take it for an inspection, and if the price is right and everything checks out, go for it.
...unless anyone here has any actual first hand experience with buying a PC car and not just an opinion.
