Used GMC trucks for sale near Mandeville, LA

Cheyenne did an excellent job. She is very knowledgeable and her feedback helped me to make the best decision at the time of purchasing the vehicle. I highly recommend Cheyenne to be your sales person.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Great experience on the purchase of our 2026 gmc 2500. Would like to have recieved our paperwork for our purchase upon delivery of the vehicle.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Went in to get and oil change and I had a great time while I was waiting. Free Doughnuts and orange juice.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

I was traveling through the area and had issues with the car overheating (auxiliary fan was not coming on [faulty relay]). The issue was diagnosed and fixed in a timely manner. I could not be pleased with the empathy which was shown knowing we were stranded and needing to get back on the road. Staci, Mike and David went over and beyond to see that we were fixed and ready for our 12+ hour trip. I am/was so pleased with the work that was performed on the vehicle. I am always looking for individuals like these, who want to make sure they do/did everything they can to make sure the customer is take care of.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

I Don?t Trust My Car With Anyone Else. When I First Started Going There, They Were So Polite. They Made My Us Feel At Home. I Never Go Where I Don?t Feel Welcomed. Awesome, Staff

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

The oil change and tire rotation service went well. I have always taken my vehicle to get the oil changed since I made the purchased from Ross Downing. Great service and very professional.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Great service, Great sales, had a wonderful experience with both sales and service. have bought many vehicles with the rainbow family and always have been treated right.

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Awesome experience all the way around. Pleasant staff and excellent customer service. They promptly addressed all my concerns and provided solutions taking care of all issues.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

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.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

My experience in the service department was great. Tracy was very kind and helpful and kept me updated on my vehicle’s status each step of the way.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

I had a such a wonderful experience purchasing my 2021 bmw x6 in January. I had no plan of getting the car I thought I was going to experience another rude salesman’s so I was just going to see it in person and really didn’t want to talk. I was totally wrong. Jayson was amazing and very professional. He had lots of patience with me. Jayson’s energy was amazing, so much so where due to unforeseen circumstances I was shopping for another car.. Since I had such a great unexpected experience with Jayson I said I have to go back to him even though the dealership is 1 hour and 15 minutes away from me and I was referred to another dealership 15 minutes away from me. I called him and said Jayson let’s make magic again after telling him what I was looking for.. Well yesterday that was what we did. I purchased a 2023 bmw x6 with the M sport package (my white diamond) Jayson once again was simplyyyyyy amazing, alone with MrJR, one of the managers, Mr. Bobby another manager and Mr. Don the finance manager. Thank you guys so much.. Jayson was a call away and talked to me while he was off.. I told Jayson I wasn’t taking that drive to the dealership unless we could make magic with that car, he said don’t worry we will and we DID💃🏽 Another great experience . Wonderful people who made a horrible experience turn into an amazing one that was worth the drive anytime.. Looking to get a car definitely ask for Jayson Robertson, he is truly that guy!! I’m a loyal customer because of him I took that drive to the dealership because of him Im writing this review because of him…Jayson thanks again for making magic , you rock dude!!!

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?

The sales person was excellent. The finance manager was very nice but just had a longer wait. Selection of cars was excellent too. Very happy with our purchase.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

We bought our 2nd Tacoma from Joey C, got the 1st one in September 2024. I highly recommend this salesman and dealership, so much better than either of the dealerships in St. Tammany Parish. If you are looking for a great deal with no xx and excellent service after the sale this is the place!!!

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

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.

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Nice place. This is a nice place to find a car a lot of choices and the staff was so very helpful in my car buying adventure. I usually hate having to buy a car. Almost painless.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Sales ambassador Evan and the crew at Lamarque Ford did a great job presenting an excellent lease offer, without the needed to go back and forth with negotiations. Very professional, well run dealership - highly recommend!

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.
