1,200 mile service. Any suggested dealer in Ga?

[georgia_dawg]

Having read quite a fee thread about 1,200 miles service, I was wondering if I should just take my car to the closest service center or if there are any dealer that I should take this to. Seems that some dealers are more familiar with M cars than others since there aren't many M's around.. I live in duluth Ga which leaves me two choices(united gwinnett, or united roswell) as far as distance goes.. Any thoughts on this?
