It’s just math.

It’s just math. Huge thanks to Jason for his commitment (pretty sure he got his steps in walking to the booth a hundred times!) and to Cesar for making F&I quick and painless. We drove up from San Clemente to buy our car and will happily keep making the trip for service (and for the bonus stop at Vince’s Spaghetti)

Sebastian Sanchez was our sales guy.

Sebastian Sanchez was our sales guy. I don't see anywhere to give him 5 stars, so I'm doing it here. He was excellent!

Excellent service from the sales personnel and

Excellent service from the sales personnel and management. They made every effort to maximize any possible discounts and was comfortably negotiable on the price of the vehicle. I had the displeasure of visiting one other Chevrolet dealership, which was very pressure oriented. I would not only return to Mark Christopher for a subsequent purchase, but I would also recommend their dealership to any of my friends.
