but they are an Hour away... SO I mean thats what your looking at with that. There are other shops closer to Gwinnett though, Modavi, AAP motorsports, Balanced performance, are some of the ones i know about. I was referred to mainstream by a couple people, and So i have had my work done there... Good people, so far seem to be nothing but up front with you. And the prices are great. Haven't had any problems yet that I can pin point to them so a +1 for Mainstream for the moment.
