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.
We had such a great experience buying our car! The entire process was smooth, easy, and stress-free. Our salesperson, Cynthia was friendly, knowledgeable, and never made us feel pressured. They took the time to answer all of our questions and made sure we were comfortable with everything before we left. Roy was also helpful with the numbers and Cesar helped us in finance. We absolutely love our new car and would definitely recommend them to anyone looking for a great car-buying experience!
Excellent people and experience. This is our 4th vehicle bought there. As anyone we do not look forward to a vehicle purchase and wait time. But these guys and gals are great.
Great experience. Easy, timely, and efficient. Nick was helpful, and professional. Very happy with my purchase
My wife and I dread buying cars...but our entire experience at Mark Christopher Auto Center was OUTSTANDING. Jose was honest, personable, communicative, and we had a good time cracking jokes the whole time. We felt like he understood exactly what we were looking for and had our best interests at hand. He didn't waste our time, and made the process very smooth. On the finance side, Jason was a delight to work with. He was able to help us navigate the paperwork quickly, and like Jose, we found Jason to be very trustworthy. We love our new car and couldn't have asked for a better experience. Thank you guys for taking care of us!
We had such a great experience working with Cynthia today! From start to finish, she was friendly, professional, knowledgeable, and never made us feel pressured. She took the time to answer all of our questions and made the entire car-buying process easy and stress free. We truly appreciate all her help and would definitely recommend her to anyone looking for a new vehicle.
I have purchase two vehicles from Mark Christopher Chevrolet. My experience has been great. They are friendly and don't pressure you. I have even taken my truck in a few times and Avo in service is GREAT. He listens to you on what's going on with you vehicle and takes detailed notes so that the mechanic knows exactly what's going on. I am a very picky person and it's nice to see a stand up dealership. The sales department was nice, understanding and works hard to get you into the car you're interested in. The service department works hard to fix any issues with your car, new or old. In a few months, I will be purchasing a new Silverado and I will be going back to this dealership.
Had an absolute 5-star experience working with Anthony and Albert! They were super helpful, transparent, and made the entire buying process smooth, straightforward, and genuinely fun. No unnecessary pressure—just honest, top-notch customer service from start to finish. If you are coming here to buy a car, definitely ask for Anthony and Albert
Working with Chelsea has been easy and smooth, she is helpful and she follows up with me with updates on my car Unfortunately, the problem with the car is not fixed yet and I still have to take it back tomorrow
