Hi everyone , looking at a 118d m sport coupe it has 150,000 on it good history and in decent nick , no history of timing chain replacement , and previous owner stated no clutch replaced in her ownership, what's it going to cost to get these things done , car is cheap enough but don't want to sink too much into it straight away .or possibly buy one that's had these big jobs done and spend a bit more What's the general things to look out for ? Thanks sam
