Group 1 GMC Southwest review
I was very undecisive for about 3 weeks but my sales man
I was very undecisive for about 3 weeks but my sales man stuck in there. When I finally made it to Houston he took the time and drove me across town just so I could test a car I thought I liked. And I made that purchase that day within a couple hours
