I plan to buy a new 2015 428i as my second car. For the style 428i xDrive Coupe, I got a quota about $40894.0 from local dealers. It is not the best one compared with some shared prices by others in autopriceshare. However, Since it is lower than invoice price, I think it is fair. My last car is 2005 IS 300 and it is really reliable. For the 2015 428i, I want to know more about its reliability. In your opinion, is 2015 428i xDrive Coupe reliable? Are there any common problems with this model? In addition, are there some room in the current price? Thanks, friends
