I don't have firsthand knowledge yet since I don't have my SS, but I started a thread on my club's board requesting dealer service department recommendations in the N. Texas area and a few members gave a green light to El Dorado Chevrolet in McKinney
. I'm going to start with Huffines Chevy in Plano but red or green is yet TBD.

This thread's a great idea, and hopefully more North Texans will chime in.
