New and used 2025 Chevrolet Suburban SUVs for sale near Diamond Bar, CA

My sales AD was great to work with! He was no pressure, no hassle. He was patient, knowledgeable, and easy to work with. I got the car I went to the dealership for and left very happy. AD is the reason! He went above and beyond to make it a great experience.

OK, so I have owned 2 previous suburbans (2002 & 2013), so the 25 is an amazing upgrade to both of these! First of all, we do a lot of highway miles and the ride is simply amazing! It rides more like a luxury sedan than a truck. Since this is our primary vacation vehicle, we were careful to order 18 inch wheels, as they have a much smoother ride versus the larger ones. I also love all of the new cameras, which is a big help in tight situations. Also, the adaptive cruise control and lane assist make long road trips easier and safer as well. I also love the new exterior design features, particularly the front grill and the aerodynamic wings on either side of the rear window. I'm a bit surprised that those small design features have really updated and enhanced the look so much. The only real disappointment, so far, is the owners manual was really poorly done. Information is difficult to find, nonexistent and they even neglected to put in the required scheduled maintenance requirements (what were they thinking?). Overall, our first impressions on this vehicle have been superb and I would definitely recommend it to others who need a large family/vacation vehicle!

Love this vehicle. Adaptive cruise is great on trips, the adaptive air ride suspension is incredible. Fit and finish is great. The 6.2L has great performance. Seats are firm and very comfortable. The 10 speed trans handles the power well and is very smooth.

I was treated like family Javier/MGR was a big help Juan /sales guy was wonderful

I brought my car in with concerns that the issues I was experiencing were significant. Thankfully because I do keep up on maintenance and Sierra Chevrolet does such a great job, the issue was not bad. Joe assured me that they would thoroughly check everything, keep me informed and had my car back to me in a timely manner.

First time customer, well taken care of. I will be back. Went to another dealership for service and was told my car would sit for 10 days before being looked at. J Star had my vehicle back to me in 3 days.

Enjoyed my experience here at this dealership. Came out with a brand new car! Anthony was extremely helpful and guided us to find the car we were looking for.

I made an appointment to meet with Albert to view a pre-owned car. Upon arrival the car was out front, and Albert was waiting for me. After driving the vehicle, I decided to purchase it. The purchase was easy and fast. I recommend Albert as the purchase experience was enjoyable.

Fast service. Went in for a recall after purchase 3 months ago. Was out in under an hour

Amazing service here. Bianca cashier great service. Thank you all for the amazing service here 🙏

Alex was a pleasure to work with throughout the process. When I expressed my concerns about covid he kindly agreed to wear a mask and arranged for the process to be conducted outdoors as much as possible. He also expedited the sale process because he understood that I needed to drive the vehicle back to the SF Bay Area that day. Lastly, he was very knowledgeable about the Suburban that I purchased, and provided me with a lot of great information about its features and benefits. I wouldn't hesitate to work with Alex again, or to recommend him to others.

Service Rep - explained everything well and was thorough. Helped me take advantage of the deals they had on four tire replacement. Service saw a small leak in my coolant tank and I was able to come back the following week to have the warranty cover the work

Mark Christopher GMC is an amazing Auto dealership. No sales pressure and terrible prices. Johnathon Villa was an outstanding salesman that helped us get a 2022 Canyon Elevation. He took extra steps to help us find the perfect truck for us. We drove over an hour. And so glad we did. Highly recommend. And I want to say thanks again to Johnathon for making the experience great.

Overall great experience, Carlos was very patient and listened to my needs. He went over all the features of our new suburban and was a pleasure to work with.

Good service would come back again . This is the second car we got from this location.carlos and Salvador are good people and would deal with them again.
