My 2000 4.4 now has 140k miles. I bought it off a lease at 40K miles. I have to say I was very, very dissapointed to have to put almost 6k dollars into having the chain guides (plastic) preplaced a couple of months ago (over 30 hours of labor). The car was maintained at the dealer from new, and I followed the maintenance program to the tee. Based on many posts on this forum, I was prepared to have to put big bucks into a tranny at some point, but on the 4.4 I have to say I am now tainted in my opinion of BMW.

Look up the post for "My $5,000 Motor Repair". Like a girl you are in love with, but who cheated on you, I just feel like I can't trust her anymore.
