New and used 2026 GMC Terrain for sale near Morongo Valley, CA

I Love our new GMC Terrain… We had an awesome experience buying our car. The car was better than what I thought it would be!! Inside, It has great space.

I have had many Jeeps, when they stopped making the Cherokee I was at a loss until I came upon the GMC Terrain and so happy I did. Great style, performance handles great, many exceptional features, I spend a lot of time driving and never feel like it is tiring, lots of room in cabin and the cargo area. I have a new favorite, and it is the Terrain

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.

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.

I had a great experience. Jessup got me an Uber to take me home till work was done. About 4 hours till they called me and came and picked me back up and brought back to Jessup to pay the bill. I had all filters changed...fuel injection system serviced..this was my 40,000 mile service to bring everything up to standards.

Great work Ryan! Very thorough in providing exceptional customer service thanks for resuming wash activities after the abundance of rain this season

Very easy paperwork and pleasant staff the sales lady Michelle was very helpful with the process also Gary the salesperson is a nice and will help out when needed

We've had only the best service with Diamond Hills. Everyone we have come in contact with over the last 2 years has been pleasant, courteous and helpful.

I didn't have an appt but they were awesome anyways. But nothing breaks on a schedule lol. I was helped quickly, offered coffee and a seat. They kept me updated on the car and how long it'd take for the parts. Thx guys, great job as usual.
