BMW of the Main Line

I hate BMW of the mainline services, their staff and SA are all unprofessional morally doesn't know how to approach customers a decent manner. I have a 2007-750Li, whenever I take my car there for servicing my SA will always makes a condescending statement to relegate me that so pervasive. After every servicing, is always something little that goes wrong, and they treats my car like a trash leaving it dirty both in and out, no regard most of are pompouss and very uncouth. My SA, is a generous guy at time but overall he okay. Recently, one of their tech damaged my amp causing three of my speakers soundless and refusing to responsibility for it, but we going to end up in court soon. Actually, I do like the place is accessible not far from where I live, and they always give me a loaner, my SA is the one who makes all my appointment, he somewhat cool. I believed they try to do the job right on repairing, but I guess they all have a marketing scheme, no matter where you go most likely will be the same or worse. Thanks to dezii!
