Bruce made our truck buying experience one for the books.

Bruce made our truck buying experience one for the books. From having the multiple trucks we were interested in pulled up and ready to view, to making sure the deal was worked perfectly. We will recommend both Legacy Westbank and Bruce to anyone in the market for a GMC.
