New and used 2026 GMC Terrain for sale near Montclair, CA

Fantastic dealership with professional and courteous staff.

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.

Professional and superb customer service. Was dealing with a check engine light. They go out the way to make sure customer is taken care off.

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

Ok so I am sure my 1st review is not gonna be deleted but I have a new review for them as they have addressed my concerns and Because of 1 persons actions I am completely satisfied with the repairs and commitment that JOHN in service has made sure I was completely satisfied with the repairs so a big THANK YOU to John and anyone else who worked on this I will definitely be taking my truck back for service

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.

I needed a 10k basic service on my vehicle. Everything went well, I will use Hatfield again.

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 personally had a great experience at Hatfield. No haggling over small stuff, no arguing or fighting over numbers. I highly recommend Hatfield.

Had to get some warranty repairs done. Jeff took care of all the processing and we were informed about the progress from start to finish. Professional, courteous customer service.

I had probably the easiest, most hassle-free experience buying my new truck. Kaylynn was very accommodating and found my perfect truck. I couldn't be happier!

Great service friendly and helpful had my Yukon worked on warranty service Ceasar Rivas was helpful and took the time to call me on every step.

Good job, Great service, thank you. I will alway bring my car here

The experience was great. Worked the numbers over the phone and nothing changed when I arrived onsite. They value creating long term customers.

I called the dealership and spoke to Gary Koch. I found him to be very personable and knowledgeable. We discussed the online price and agreed to purchase the car. I am not local and handled the preliminary paperwork over the phone. Once everything was confirmed I booked a flight and Gary offered to pick me up. I was in and out of the dealership in less than 90 minutes. Gary made the car buying process super easy and enjoyable. I also received an exceptional deal.

Great customer service! Luis and Robert Salinas were AWESOME throughout the whole buying process . I would definite recommend this dealer to anyone looking to buy a great vehicle along with excellent customer service .

Michael Jacobs made the car buying process seamless when I purchased my 2025 Yukon AT4 diesel. He was extremely helpful and polite😊 Rod Shelffo in Finance was awesome to work with as well!

Staff was friendly but i left without being able to have my app hooked up to my car and I was looking forward to that feature
