pc dave - wow thats a lot of information, and i believe i have a deeper understanding of BMW's now.
i have a thing for E30's and M6's, and if i do get a BMW it would probably be a E30. however, correct me if i am wrong, some M cars weren't given the M badging correct? mainly i am talking about the M6. i heared the 635CSi is basically the M6. but hearing from your information it might be that it did not recieve one of the 3 catagories to consider it an "M" car. does this apply to the 8 series as well? 850 something comsidered the M8?
i have heard a bit on the L6, i believe its leather everything (and i mean everything), and has a nice mini fridge in the back
