Yet again, Charlie comes to the rescue!!! I went to Bimmersport because my subframe was clunking really really badly!!! Charlie changed all 4 rear subframe bushings and changed my diff seal for $450!!!!!! The dealership gave me a quote of almost $250 for parts and 15hours labour, for a total of $2000.00. This is not the first time I've had work done by Charlie, and definitely not the last. His prices simply can't be beat, and the quality of work is superb- my car has never felt better. He even took the time to look over a few things to make sure I dont run into problems in the near future. I recommend Charlie for anything and everything BMW related- you won't find a better mechanic anywhere!
