I'm always pleased with Mossy, but this time they went beyond all expectations. The issues I had with my vehicle was very challenging, but Mossy never gave up (a BIG THANKS to Jeff, he's the man). Mossy called in a GM engineer.....WOW. Problem solved! I tell you this dealership treat their customers like family.

Curtis Gasper was super nice and easy to deal with and
Curtis Gasper was super nice and easy to deal with and didn?t pressure me. I got the truck I wanted at the price I wanted. Kirk Dominique in Finance was also super nice and did not pressure me to purchase add ons that I didn?t want, and he negotiated well on the ones I did want. It was worth the hour drive.
