 I bought my 1998 BMW used in 2000 with it being certified pre-owned.  My car first overheated and the passenger side window stopped working within the 1st year that I bought it,but I only had to pay $50 to get it fixed under warranty. My car overheated so many times it's stupid. I was so scared that my eyes were always fixed to the temperature gage. I replaced the radiator, many hoses, reservoir tank, water pumps, plus the sunroof is stuck, trunk only opens with the key due to the inside buttons not working. This would be a great car if it worked half the time but it was so unreliable that I had to give up on it.
