Century BMW in G'ville, is not my fave dlr, based on older anecdotal history, and simply from a 'crummy service' viewpoint...maybe they have improved.
I called my Indie, in Asheville, (an hour and change north), and he rec'd this G'ville local indie, fwiw:
Bimmer Specialist Incorporated, Greenville, SC : Reviews and maps - Yahoo! Local
Meiac, a frequent poster here, lives in/goes to the U in G'ville; maybe he will offer up other local opins.
