Not really an MB question, but I have to ask.

Does anyone have any expereince with the BMW E31's ? I have the opportunity to pick one up (it is a 6 speed), and I have always liked the looks.
V12 power is tempting also.
My concerns are reliability, and cost to maintain, as well as any common flaws. I have done some research and all I could really find was the DK motor issues.
If anyone has owned one I would really like the details on these cars.
Not to worry, I will most likely keep my MB as well.
