Love Jacob!
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.
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

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.
Diesel AT4 it!
GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

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
Perfect for us!
As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family

My wife and I went to NISSAN OF PICAYUNE to look for a small car that gets great gas mileage We met with one of their sales personnel, miss Summer Favre who assisted us in finding the right car for our needs, we found a 2024 Nissan versa, White in color she went along with us on a test drive, and explained all the features of this vehicle. Miss Summer was very professional, friendly and knowledgeable of all the details and features that she explained to us. We ended up purchasing this vehicle, all staff, including sales manager, finance, personnel, and miss Summer We’re so professional, friendly and knowledgeable that I would highly recommend anyone in search for a good quality vehicle to go to NISSAN OF PICAYUNE! on a scale from 1 to 10, with 10 being the highest, I would give this dealership a 10, and Miss Summer thank you for your kindness and support assisting us with our purchase, you deserve a BIG 10 !

We drove 3.
We drove 3.5 hours to buy a car from Alvin at Matt Bowers Slidell, Alvin was super nice and very helpful I think he would have given the shirt off his back if I had asked for it. Alvin went above and beyond to help make the buying process as easy and stress fee as possible he treated us like family. I would also like to thank Steve the General Manager, and Tony in finance they were also very helpful in making the process as smooth as possible. I would not hesitate to buy from them again and plan on making another purchase in the near future.
Surprised myself and bought a GMC
I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

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!
Awesome trucks
I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.

Mandal GMC and Buick has got their act together!
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!
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?

My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.
