New and used 2026 GMC Terrain SUVs for sale near Mandeville, LA

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

I’m 56 and I’ve mostly owned trucks in my life. Out of the few cars that I’ve owned this 26 terrain elevation edition is the best car that I’ve owned. It’s comfortable and expensive gets good gas mileage plenty of room inside well designedand GMC has been a reliable brand for me over the years. I do recommend this car.

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

This is a very beautifu vehicle, very dependable but the gas mileage could be better. With all of the new technology, it is somewhat difficult to remember all of the various control panel options. Also the owner’s manual is very skimpy.

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

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.

The service was excellent and all Employees were professional and kind to work with. I highly recommend Mossy for purchasing a new vehicle or to have an existing vehicle serviced.

Great and easy no stress or presure, fast and friendly very informative and had us out of there in no time love my new truck

Greeted promptly, confirmed 11:00 am appointment. Was surprised with tire lugs up sell. Authorized purchase due to safety concerns. Satisfied with oil change and tires rotation services.

I purchased a 2025 GMC that was used which was listed online. I got an immediate response when I texted and they were very helpful in providing information. I feel I got a good deal. They handled getting the vehicle shipped to NC. I’d highly recommend Crown and Brandy (sales).

Joseph Grego was a very helpful salesperson. This was our second purchase from Crown Buick through Joseph Grego and we appreciated doing business with him.

Amazing experience! Everything was transparent no surprises, was worried about the long drive and having the dealership change things up on me but no everything was perfect. My sales man really is a down to earth gentleman, he went above and beyond for me and really hit a personal level of trust! Kimble wright is a name I will never forget based on my experience at this dealership.

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.

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

Rainbow Buick GMC in Covington LA has certainly set the bar for customer service! Never have I had such an excellent experience at a dealership as I have at this business.
