Fantastic dealership with professional and courteous staff.

I have 2 vehicles within 2 years from same dealership. no mark up like other shaddy dealership and not to push of the stuff that you are not comfortable. Highly recomend this compare to other price gauging dealership. As usual my service advisor josh is amazing and never push for anything that is not needed.

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

Great experience. Simple and easy. Great staff. Definitely would recommend.

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.

Jack in the service department came through for me in getting my front and back brakes done in a timely matter. Always responded to my calls. Awesome customer service.

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.

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.

First time buyer 12/12/2024 ..JP was able to help me with all my questions and needs to purchase my new sierra pro ..thank you JP you're awesome

The service staff were friendly and efficient. My car was serviced (oil changed and tires rotated) and ready in a timely manner. The waiting area and rest room were clean

The whole staff, sales and service are friendly, helpful and honest to deal with. They take care of your needs.

The prices attracted me. The customer service and experience/ level of knowledge was not great. There was an inconsistency of dealership policy. It would be nice to get a car for the price you expect. I felt forced to purchase items I did not want

Experience was excellent! Everything was so smooth and easy! We are so happy with our purchase! Highly recommend Danny from GMC! Customer service was on point!

My experience at the dealership was excellent from start to finish. Abraham greeted me right away, took the time to understand what I needed, and answered every question with patience and detail. The entire process was fast, smooth, and professional. I truly appreciate his outstanding service and the overall efficiency of the team.

Tustin Buick gmc went above and beyond my expectations. Super friendly and helpful staff. They were able to answer all my questions and concerns. I would definitely recomend buying a vehicle from this dealership. Thanks again Tustin Buick gmc for all of your help.
