Our Reviews
The reason for 4 stars and not five stars cause when I arrived with my mom, we had to wait a while for Taylor our salesperson to meet us. Apparently he was coming from another building. But the real reason was the receptionist at the front desk that we checked in at. After waiting for so long, we asked her how much more time. She was not nice, in fact called my mom out as being very rude. Than there was a guy she called over and was talking to about the whole ordeal that was staring at her which made my mom very uncomfortable. We did not get the names of both of them but did bring up to both Taylor, his manager and also our finance person. September 18th, Friday around 4pm was when this happened so maybe u guys can find out who they were especially the receptionists working that day.
The dealership was very nice and clean which is great as a customer to see it was well maintained. My sales representative JC Cavazos was amazing to work with. He made me feel very comfortable when going through my options and he was also very knowledgeable. I am thankful to JC as he is the reason why I bought a car through Mark Christopher.
A big thank You to (Gerald waters) and (Finance) they did a very good job very professional you can see the years of experience explain every detail of the car little struggle in finance part but other than that made it happen very professional very clean place 10000% recommend

Best and easiest car buying experience ever! Taylor and Greg were both great to work with!
The Salesman who greeted us outside, Jesse, was friendly, informative, listened to our needs & found me the exact car I was looking for. Larry Lee helped us with all the financials & did an excellent job!
I have been very pleased with the service provided by this dealership. I have been there multiple times and they are always top notch. One of the biggest things is that they always give a call back when they say they will, which is unlike many other dealerships that don't, and you can't get a live person.
Devin was great. His communication with me during the whole week was excellent. Devin didn't give me the run around with prices like some other dealerships did. And it seemed like he made me a top priority.
