Hi. I have a 320 & all i can say is that you will in time have the door closing aid fail & also the heater blower regulator will fail. This aside it should go on for ages with proper servicing! :lol

The engine's timing chains break and that wrecks the valves, cams etc. The chains are good for 120K+/- miles after which, some say, one is on borrowed time. Try to find out when the chains were replaced or, if unknown, have a shop check the chains' stretch as a wear indicator and replace them if in doubt.
