Is the reliability really as bad as they say?
Hey guys, looking into maybe getting rid of my ZHP for an 03 M5 (assuming everything checks out), but potential reliability issues have me a little concerned. I've heard all sorts of stories about how M5s are a nightmare to maintain, but I've never seen any specifics (and when I search, information seems to be too scattered to really understand thoroughly). I'm prepared for an increase in maintenance costs, but will the car have a lot of down time? Is the maintenance generally DIYable? If I'll end up having it in the shop more often than I can drive the car, I'll probably try to go for a 550 M-sport. The E39 M5 has been my dream car for a long time though, I'd much rather get into one of those if it's practical
Thanks for any advice you can offer
