I don't know what's going on with this cars. The noise inside my car is never ending. We brought it to the dealer several times to replace the seals on the four doors. Acceleration is very, very, extremely poor in the 525i. You can not pass a car in the city and mine is standard transm. My a/c always smells so bad that I always prefer driving with my windows down... for the price you pay? No way! This is a 40K car! I drive very poor.
