Great experience. This was our 3rd vehicle bought from Mark Christopher Chevy. We will be back for our next vehicle.
First class service every time I visit. Always informative and helpful with all my vehicles needs.
Amazing atmosphere and truly genuine nice salespeople! It was a pleasure doing business with them!
Went above and beyond to try to get me the car I wanted even attempting to go to another dealer to get it.
My service advisor Caesar Cardenas was very helpful. Always texting me back with information regarding the update of my truck offered me all kind of dealer. Coupon, discounts, clean and friendly staff.
I want to thank Chelsea Jose for always offering me the very best service. You all have a great person working for you.
Joel was our Salesman, and he did an amazing job making sure we got the car we wanted. We bought a 2026 Chevy Tahoe with much more add ons than we could have asked for. Thanks to Joel and the sales manager for making this happen for our family!
The staff was very professional and courteous to deal with when purchasing a vehicle from the dealership.

Jose was excellent and helped us with the truck we came to see. Everything moved quickly with our purchase. The dealership was very helpful to get us in and out in a timely manner. I am very pleased with our new vehicle purchase with Jose and dealer.
First impression was great. We were met by a salesperson as soon as we got into the lot. When I decided on the vehicle I wanted, the contract signing went pretty smoothly. Once they had my signature and down payment, it seems staff was no longer interested in our presence. I waited over a half hour after the final signature to be met by the sales person to be handed my key or told where I can go to take possession on my vehicle. Then I waited an additional 15 minutes to find our sales person to be handed our 2nd set of keys, which he said he would be bringing out right away. We in fact had to have someone else reach him by cell phone to get him back to the from to retrieve the 2nd set. How quickly they forget about the customers once they make a sale.
