I'm like mkeddie. I do most of my own, but bring it to the dealer for the scheduled warranty stuff - I got that in the purchase deal anyways. So far my dealer has been great. Replaced the two lower ball joints on my 2010 550 with about 400 miles on it. I'm not sure what to think about that - hope it's not a regular thing though. I've got about 4 months to go on my warranty then I'll be doing it all.
