Used GMC trucks for sale near Mandeville, LA

Mostly always a heart breaker! Have stated this many times before...to no avail! No initial person assigned to place a paper mat on your floor and collect your keys or move your vehicle to a unconscious location..no service rep to greet you with your request etc etc...

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

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.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

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.

First time at bills car lot I love it I got what I wanted everybody hospitality was amazing I love the role everyone played I would most definitely highly recommend

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.

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

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 had a very good experience at Lakeside Toyota with sales agent Leonard Young. His professionalism was outstanding and very knowledgeable with my vehicle purchased & operations (2025 used Chevrolet Tahoe) on 4/30/25. His customer service and mannerism was top notch as well. Most definitely will spread the word to family and friends if looking for new or used vehicles especially Toyotas! Also, the financial advisor Jessie Johnson I would rate him the same. They were a dynamic duo! Thanks guys!

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Alfred Taylor is amazing sale person! I would recommend everyone to see him at Honda dealership in Slidell. Once again, Thank you Alfred for finding amazing cars for me and daughter.

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 were greeted instantly and we stated what we needed and he took the car to a service bay. We waited in their beautiful waiting area and in 45 minutes the car was ready. Everyone was friendly, professional and speedy. We have purchased our Hondas and had them serviced there since 2018. Never a bad experience.

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

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.

Ross Downing in Hammond - Cameron was an amazing salesman! He totally went above and beyond. I highly recommend them! If you go by, be sure to ask for Cameron!

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.

Our salesman, Landon Crane, is new and even didn’t have his business cards yet but he’s gonna go far. He was extremely polite, willing to answer questions and had no problem getting up to ask about an answer he wasn’t certain of. I appreciated he wasn’t pushy, condescending, or fake. He may be young and just getting started but you won’t go wrong by requesting him for your salesman. The young man knows how to give an appropriate handshake on top of all his other positive qualities. From start to finish it was a relaxed buying experience. Give him a call!

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 !

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.

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!!!

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.

Excellent experience!! As a woman buying a vehicle on her own most of my life, I have had some disappointing experiences but not this time! I highly recommend Gateway Ford!!

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.

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?

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

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.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Overall best Dealership. All boxes checked. Salesman Rodney Batastella, finance Timmy Genusa, sales manager Clint Favare. Purchased several vehicles from this dealership. It’s crazy easy and quick. Most courteous ever. Happy place to buy a care.

Great experience. More than I anticipated on trade in. Very friendly Internet and in house salespeople! Thanks Lenny and Ray,

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.
