Hi Bud, is the car still under factory warranty? If so, you've got nothing to worry about. If it's a Starmark car, even better. About the only thing I've seen that would worry me from an ownership standpoint is the number of catalytic converters that need to be replaced. They start by making a rattling noise due to the broken pieces inside the "cat". The noise can get quite loud after a while. I've even seen a few cases where the broken pieces actually restrict the exhaust flow causing multiple mis-fires. Although replacing the cat(s) is an easy DIY job they are EXPENSIVE. The E class cars are not the only ones affected though, it seems this happens to 112 and 113 equipped vehicles, including ML's. Anyhow, I think the W210's are great cars. They're fun to drive, nice to look at, and easy to work on. Good luck
