Re: new owner with door question
congratulations on becoming an M5 owner. I've owned mine 4 years, and would not consider selling it.
I could be wrong, but I recall all US E34 M5's with build early dates through 1991 were classifieds at 1991 models. I do not know what the earliest US build date is, mine is 7/90.
as for the console handle - people occasionally part out M5's on e-bay. Have you checked with a dealer to see if it's still available ?
door panel - I have not pulled the panels on my M5, but I have pulled the panels on a 1991 735i, and those two cars are similar in many ways. If the M5 rear panel is like the seven series - there is a plastic male tab on the door panel and a female receptacle in the door near the door handle. Pull up on the door panel to release the receptacle from the door. Once the door panel is off, the receptacle is removed and re-installed on the door. When you re-install the door panel, press the panel outward to re-engage the plastic tab.
