2006 Z4M coupe with 115,000 and I drive it every chance I get.
I had one semi-major repair that I believe was needed before I bought the car 7 months ago. It always had this sort of crunchy sound that would come from the rear diff. One day it started clunking terribly like someone was hitting the drive train with a sledgehammer when I put it in gear. Managed to limp it to my mechanic and found that two diff bolts that hold it to the frame were out. This caused the axle shaft to work at a bad angle and it went out. A new axle shaft and a couple of bolts and it's good as new. Not so bad as I assumed I would have to fix something on an 11 year old sports car with over 100K miles.
In my commitment to drive it as much as possible, it got up to 50 degrees F this weekend so I took it on a nice long drive on Saturday.
