Mark Christopher Chevrolet Buick GMC Cadillac review

Alex is great!

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.

Best Truck buying Experience

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.

KEEP UP THE GREAT WORK AND CUTOMER SERVICE

Adam Miller in the service department is the best! He is always very friendly, and makes sure my vehicle and I am well taken care of. It seems that nothing has changed at the dealership since it was sold. I am very happy about this. Thanks again for the great customer service!
