 Many things shoppers should know about a 3 series BMW before purchasing one. All my adult like I have wanted a BMW, so last year I purchased a used one 2007 238xi. I have had many problems with this vehicle since I purchased it, and it has costed me over $2,000.00. I have had two recalls on this BMW, and the dealer told me that they do not know how to repair the recalls. I was told that as soon as they find a solution they would let me know. I have waiting for about six months and they have not call me yet. Gas mileage on this vehicle is very poor. Things that I had to have repaired is : Oil pan gaskets,windshield washer neck  filler replaced, broken gas meter replaced ,transfer case motor replaced, radiator sensor replaced,and the replacement of the gas tank. I have purchased over ten used vehicles in my life time, this BMW is the worst car that I have ever owned. I have told family and friends not to purchase a BMW, its one of the worst cars on the market. I plan to get rid of my BMW ASAP.
