The biggest issue is that they are the ONLY BMW servicing dealer on all of Long Island. I've been to Manhattan BMW and I was underwhelmed by their service department. They were FAST, but there was always something wrong when I got it back from them. Ever since Gold Coast became a dealership and hired the best mechanic the old Precision BMW (in Valley Stream) had, I've been very satisfied with their work.
If you think BMW takes a long time with parts availability, be thankful you didn't buy a scooter made by Piaggio. According to Avi, of all of the manufacturers he's had to deal with, BMW was the best in terms of parts availability and timely delivery.
