Went to the local BMW dealer to check out what cosmos black looked like in person, and was told that I should stay away from the 850 because the 12 cylinder is a big time expense to maintain, and that if I was set on an 8, I should stick with the 840. He wasn't very enthusiastic about the 8 series at all, and sort of shook his head. My favorite body shop guy also has alluded to the problem of the electronic throttles of the 12 cylinders and said "lots of problems, expense and worries, avoid them and stick to the V8". So, what is the real truth? I,ve browsed the board and looked in the archives a little, and seem to get a varied response to the maintenece of the 850. Thank you again for your help!
