Avoid CA e39 M5?
I've been searching nationally for an e39 M5 for several months, and I've found one in northern California. I'm wondering whether I should be wary of purchasing a CA e39 M5, though, because of the lower octane you guys get.
Would I be better off buying an M5 that hasn't been used in CA?
