New and used 2026 Chevrolet Trax for sale near Diamond Bar, CA

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.

Buying my car was a great experience: Victor was attentive, courteous, and knowledgeable, and great at following up, whether he had an answer or had to ask his manager, Manny, who was also great; as was Oscar and everyone. Thanks!

Joe Jimenez did everything possible to ensure that the issue with the emissions was covered under the GM warranty. He was very thorough and confirmed with GM to ensure there would be no out of pocket cost. Need to have more service personnel like him.

Came on for a minor repair for my 2023 Chev Bolt, was presented with an offer on a 2025 Blzer I could not pass up.

Jeremy was so helpful from start to finish with my visit. Very efficient and timely making me feel important as a customer and maintained steady and open communication throughout my service. Keeps it real without trying to add or upsell extra charges and services besides what?s necessary. Makes helpful recommendations. Employees like him are why I continue to return to the Sierra Chevrolet of Monrovia specifically for my services!

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.

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.
