Radiator broke causing the headgaskets to blow around 80,000 miles. headunit to the $1300 6 disc cd player broke. Window was glitchy (when I would try to roll it down it would stop at random and go back up).
This is an overall good car. My uncles 540 radiator broke on his bmw also, which makes me wonder if that is a common issue. Other than that and the radio it held up good for 10 years. Had good power and suspension. My only other gripe is that the gas mileage was very poor in the automatic. I had to try to really hard to get 20 mpg on premium gas. That was my final straw so I traded up for a civic, which with the same driving gets 37 mpg.
Any car's radiator will "break" if it is not tended to properly. My BMW is 12 years old and has not had any radiator/overheating problems in over 140,000 miles. I have had the radiator flushed periodically, and that's been about it!
