Mossy of Picayune review
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
2025 GMC Sierra 1500 AT4 review
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?
