I generally don’t like to take my vehicles to a dealership due to their sudden found issues, more money required to fix it & ridiculous turn times. The process here was easy from scheduling online, the customer service at arrival & the extraordinary real estimated time, for a dealership service. Thank you & I will be back!
Came for an oil charge and tire rotation. Service was quick and courtious. I would recommend Mark Christopher.
They were very friendly and efficient and handled my problem in short order. Thank you

Knowledgeable service consultant, very helpful. I have been to this dealership for quite sometime for service on my car, and am satisfied with the job that they have done.
Customer service was top notch from when i walked in to when i picked up my vehicle. Service with a smile
Mark Christopher promised to have my vehicle ready in 2 days. They did not have it ready in 2 days. They had it ready in 5 hours. At a much lower price than was originally quoted. Vehicle runs like new and I am very satisfied with my visit to this dealer. My personal attendant Cesar Cardenas was fabulous
The wait time was suppose to be 3 to 4 hours but I think it was less, which was nice on my part.
Service was the best I have ever at at Mark Christopher. They were very happy and helpful to get me the best deal possible. It felt as if I was dealing with family.
Always nice, always have your interest at heart. Always make sure your service is being taken care of.
Tony Catalano made the 1 hour trip worth while. His attention to detail made the deal happen. Due to lack of inventory I had to locate the desired vehicle online hence why I drove to this dealership.
Tony Catalano And Vince Catalano, great people and fantastic help in getting me into my truck handle everything for me and I was into and out of the dealership quick (15 mins) Tony had all the paperwork ready to sign. Thank you guys, not sure if you will get a chance to see this. But great work!
