 The coolant systen of this car is the worse than I ever see, much of the parts are made of plastic, is a shame that BMW don't make it much better, cause is very expensive. Since I buy this car about a year ago 120,000 Miles 2nd owner I have to replace the complete coolant system about wich cost me about $2,000. I feel in love with the shape of this car, but I won't recoment it to any one, also the Engine is not stronge as is suppose to be. If the Engine over heat once you loose it.
