Head gasket went about 3 months after I got the car. The dealer paid half the cost of the repair! Interestingly the mechanic commented that when he had the head off there was no sign of wear (on an engine that had done well over 200,000 miles!).
Apart from that just the usual servicing and running repairs (bulbs, pads, etc.
This is a fantastic car! It is ultra reliable, very comfortable and looks great in it's glossy black paintwork. I can't believe a car that's worth only £800 could be this good! It gets envious looks from drivers of Ford Mondeos that cost ten times that.
If you want another car from this dealer you'd better buy it soon, because if he insists on warranties on 13 year old cars with 218k miles he won't be in business much longer.
These are lovely cars and good value second-hand, from a time before BMW's became too complex for their own good.
