Don't forget to check carefully for rust before buying any 210. There are quite a few threads about it. Fortunately, the 4matic spring perches seem to stay attached on all of the cars, unlike the RWD versions. But even if the car stays in one piece, you won't like seeing rust creep from all sorts of places.

Expect to replace at least one rear window regulator during the time you own the car. These are cheap and easy to replace, but a very poor design.
