Thanks for the info on carfax. I guess all my experience with carfax had been on the 8 series with no maintenance reports on the cars I had looked at (20 or more). However, several owners had excellent BMW maintenance documentation that they retained and were able to provide.
I wonder just how much effort there is on the part of the dealer service departments to do that. I'll have to ask my SA.
Have you thought more on looking at MY05/06? I am at 82k miles and the smiles just keep acomin'! I am off to another round of drives on the Tail of the Dragon with fellow 6ers (some Ms as well) in a little more than 2 weeks. Some of my best times with this fantastic car.
