Welcome to Mark Christopher Auto Center

This survey is not user friendly. My 3rd time in responding to this survey. Overview, took 3-1/2 days to repair car. During this time, picked up car only to return as engine light came on. Consultant, Ivo, assisted in getting GMC to cover engine repair cost, which is very much appreciated.

So unprofessional, no accountability gave information to someone that wasn’t owner of vehicle they open parts with my consent called them out they messaged a person that want on there then took no accountability said they didn’t my sent a message and I have prove .

Outstanding! The level of professionalism, care, and kindness that was shown to us when we purchased our vehicle was amazing. We have purchased several vehicles at this dealership and with each purchase we receive the most courteous and respectful customer service. The sales associate that assisted us (Richard) provided exceptional customer service. He was kind, honest, and professional.

I want thank Mark Christopher for the great service,professionalism kindness ,respect and honesty

You asked whether I was satisfied. Chelsea’s handling of this deserves more than a checked box on a customer satisfaction survey—it deserves your leadership’s attention. On Thursday before the long Columbus Day weekend, something struck our windshield while we were driving down the 10 freeway, leaving a roughly three-inch hole. My brand-new 2026 Escalade had fewer than 1,000 miles on it. I was 300 miles from home with my wife, two small children, and my senior citizen parents, with a vehicle that was unsafe to drive back. We were 15 miles from our destination, so we got there and I immediately started calling dealerships to find a windshield. When I called yours and asked for the service manager, Chelsea answered and asked how she could help. From that moment, she owned the situation. She immediately texted me, got to work, and within 45 minutes had confirmed the windshield and scheduled the repair for the following day. When I dropped it off, she also accommodated my requests for an oil change and tire balancing—all heading into a holiday weekend. I own my own company, which has been in business for nearly 40 years, and customer service is central to what we do. I know the value of someone who can recognize urgency, understand the people affected, and take responsibility for getting the job done. Chelsea demonstrated all three. She understood that she had an entire family counting on her. Her urgency, communication, and follow-through allowed us to enjoy our trip instead of spending it scrambling for a way home. Employees like Chelsea are assets, and assets like her need to be recognized, invested in, and given room to lead. She showed management qualities under pressure, and I hope your leadership sees the potential that was so obvious to me. Please put this in front of your general manager and whoever oversees your service department, and make sure Chelsea receives a copy. I want her to know that I noticed every bit of effort she put into helping my family—and that I took the time to make sure the people above her heard about it. Chelsea came through for us when it mattered. That deserves recognition that carries some weight.

The sales lady showing me the cars was really nice. They made the buying process easy.

I had an outstanding car-buying experience at Mark Christopher Auto Center, thanks to Devin Rangel! From start to finish, Devin went above and beyond to make the entire process seamless, enjoyable, and completely stress-free. He was professional, knowledgeable, patient, and genuinely committed to making sure all my questions were answered and that I felt confident and comfortable with every decision. What really stood out was his exceptional customer service, honest communication, and willingness to go the extra mile. He made me feel valued as a customer rather than just another sale, and that made all the difference. If you’re looking for a salesperson who is professional, trustworthy, attentive, and truly cares about your experience, I highly recommend asking for Devin Rangel at Mark Christopher Auto Center. He made what can sometimes be a stressful process feel easy and enjoyable. Thank you, Devin, for your outstanding service and for making this such a great experience! You absolutely deserve the recognition.

We purchased our car with Cynthia and she was very kind and worked to help us have a great experience.

I want to thank Nobu because he is timely and the service department does an awesome job. I will always return to Mark Christopher Service dept.

Devin Rangel made the purchasing process real smooth and quick. Devin was attentive to my needs. I was in and out of the dealership within 3 hours. Test drove the Chevrolet Suburban and completed the financial paperwork. Finance department was able to get me a really good interest rate. Keep up the good work Devin!

Great customer service.. timely work
