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.

Great follow up scheduling went perfect. Repairs were done quickly and it looks awesome.

Jacob was AWESOME made sure my problem was taken care of! Good job Jacob !

took a little while to locate the part but once it came in, installation was done to my satisfaction.

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.

Shopped several dealers and Mossy was the easier to work with finding the best truck at the best price. Handled most of everything before arriving to pick up new GMC. Thanks for making it easy.

The staff here is EXTREMELY courteous and they are diligent among all things. They are knowledgeable and they Carefully explain everything to their customers!

Love Jacob! He might be my favorite person at the whole dealership. As soon as he sees me drive up, he walks up with a smile on his face.

Fabulous, clean and fair.Friendly down to earth sales men.Praise God for making good people and sales men.When you need a car go to Mossy of Picayune. The get the job done.

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.

I like Mandal Buick/GMC! Jamie has been my service representative since buying my Yukon in 2018! Dang guys! It’s been 6 years and I’m still coming back for service. I also bring my wife’s Yukon in for service here. I highly recommend Mandal!

Mandal GMC and Buick has got their act together! Their service team is all over it - I give Sussie a shout out for your help! I give Ray my Super Man Mechanic that gets it right every time and if something goes wrong he is right there to stand behind his work and make it right! No arguments just how can I help - how can we make it work Mr or Mrs. Not only that they take the time to explain what is wrong with your vehicle! This team is focused, emphatic, and passionate about what they do (taking care of the customer). I can?t say enough! I thank God for guiding me to the team and to Mandal GMC and Buick. My 2018 Chevy Silverado 1500 LTZ, 4x4, with a 6.2 liter has over 350,000 miles on it - it still has the original motor, transmission and drivetrain; but not the original tires, brakes or oil (those things gotta be changed you know - it is called upkeep). My truck still runs like or better than it did the day I bought it brand new! I?m grateful to have met this group of people that Love what they do - helping peoplej Oh great Coffee!
