New and used 2026 GMC Canyon trucks for sale near Mandeville, LA

Been purchasing auto?s from Louie for years! Super nice guy! Go see him for your next vehicle purchase!

Hands down my best car buying experience. I will purchase my next vehicle with Crown Buick GMC.

Always get professional help...Everyone's courteous and always give excellent answers regarding service rendered.

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.

I'm always welcome and that's a GREAT FEELING and a HUGH PLUS to receive EXCELLENT SERVICE .

I'm so thankful to our salesman, Joe Grego, in helping my wife and I purchase a vehicle. We went in looking to purchase a new GMC Terrain, but it was above our budget. Joe made us feel comfortable and was patient with us in finding a 2023 Terrain in great condition and at our price point. I also want to thank the other Joe in the finance department. This was the first 'new' car purchase both me and my wife, so we had a bunch of questions. He was also patient and kind in answering all our questions. He helped us to be able to drive off in a beautiful vehicle that we could truly afford. Also, many thanks, to Joe Grego for capturing the moment by taking a picture of me and my wife in front of our 2023 GMC Terrain. He was thoughtful and respectful to ask our permission to post the picture on social media. We would not have that picture to look back on for memories of our first vehicle if not for him. I will certainly be going back to Crown Buick/GMC for any future vehicle purchases. I'll see you then, Joe.

We purchased a 2024 gmc from Taylor and Austin. Great salesman they took time with us and explained everything. This was our 4th purchase from Ross downing and wouldn’t go anywhere else. They gave us everything we asked for. Highly recommend this dealership. A thank you to Taylor And Austin. J&B White

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

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...

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

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.

Fast friendly, got the deal I wanted. Followed up the next day with a car wash and I was on my way. I plan on using the maintenance department for oil changes in the future.

I purposely waited a couple of months before writing this review because I wanted to see what kind of follow up Rainbow did and I wanted to go through the first service of the truck with their service department. I purchased the Sierra 1500 truck with the small diesel engine in April. It has been a fantastic truck so far and I am getting over 30 mpg on the Causeway. First, it was a pleasure dealing with the salesperson, Rocky Comeaux. She was not pushy, she listened and she answered questions. There were two questions that she did not know the answer to - and instead of making up a response, she asked someone in her department. Having been in sales at one time for 8 years, this was refreshing that a salesperson did not try to "look good" in front of the customer and not look like she did not know what she was doing and made sure my questions were answered correctly. Rocky has followed up with me several times since the purchase to make sure that I was satisfied with my purchase. Second, I traded in a 2004 Dodge Ram truck with over 360,000 miles with the original motor and transmission. I take care of my vehicles, and longevity of the truck was important to me. As such, the long term warranty options were of interest. Rainbow explained them, and they treated me fair on my trade in. Third, paying for the vehicle was easy and picking it up was seamless. Fourth, I recently brought the truck in for the first oil change and service. The service department was booked for over a week but getting the appointment was easy on the app and I picked up the truck later that day at my convenience. The only hiccup on the service was that the DEF was not refilled. When I brought this to the service department's attention, they immediately apologized and filled it up asap. The service department was very easy to deal with and very friendly. I would highly recommend this dealership. This is my second vehicle I have purchased from them as we have a 2013 GMC Suburban still going strong.
