I had a very early '08 e92 M3 - Only issue I had was the techs in the service department aren't that great, so unless there's a documented issue by BMW they don't know how to fix it. For example - I had the issue at slow tight turns of the clutches sticking in the LSD, turned out all they needed to do was use a different oil in the LSD. Problem with the service department is it took them over a week to replace almost the entire steering system..... What??? yea, that's right, even after I brought it in and told them where the problem was they worked on the wrong side of the car. Gave it back to me and told me it was fixed. It took a while and eventually a bulletin came out from BMW and they finally learned how to fix my issue
Aside from that I had no early model problems
