Thank you to the team Mossy of Picayune!
Thank you to the team Mossy of Picayune!! Special thanks to Adam, Roy, Kirk, and Karissa. They made my car buying experience smooth and transparent! The staff were friendly, knowledgeable, and genuinely cared about getting me in the vehicle I wanted!! Adam took the time to answer all my questions and made sure I was comfortable with every step. The finance team (Kirk)also went above and beyond to get me a great deal and explained everything clearly. Mossy of Picayune really values their customers — the level of service and professionalism here is top-notch. I absolutely love my new vehicle and couldn’t be happier with the experience. Highly recommend to anyone looking for a dealership that treats you with great care, go see the crew at Mossy of Picayune

Bought New GMC Canyon AT4
Visited local dealers that included Ford, Chevy, Nissan and test drove vehicles at each but was surprised by the GMC Canyon. I originally wanted an F150 but price, size and quality issues made me rethink that purchase. I test drove the only available Ranger within 100 miles and did not like it as much as the Canyon. Staff was straight forward. No back and forth. Easiest car buying experience I've ever had.
