Always a great experience
We love Lenny and Tom- every buying experience we've had with them has been a smooth one. I've been purchasing g vehicles from Lenny for over 20 years.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

let me start by saying that I hate car dealerhsips,
let me start by saying that I hate car dealerhsips, period, but with that being said, I recently met with Zahra at this dealership and had a very good experience. Zahra was professional, knowledgeable, and easy to work with. She took the time to understand what I was looking for and made the whole process straightforward and low-pressure Overall, if you're looking for someone who is attentive and easy to work with, I would definitely recommend reaching out to Zahra. Thanks again for the smooth experience!
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

I just want to say that I had a very professional
I just want to say that I had a very professional customer service experience with Ryan Ramdass and wanted to write a review to express my gratitude. Ryan and I had an issue that we had to address and resolve over the phone and he handled it very professional and cautiously. I would recommend Ryan to anyone who is searching for their next Chevrolet! He is a top notch salesman in my book. I his straight forward and to the point and says it like it is and I appreciate that about him and our conversation. Ask for Ryan when you look to purchase your next car he will not let you down. Aaron...
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

I found my car on the internet and scheduled a test drive
I found my car on the internet and scheduled a test drive with Kiara. I was her first potential customer. She did a great job even though I might have scared her on the test drive. I ended up coming back after I sold my truck and was able to work a fair deal after some good negotiations. Part of my negotiation was to bring my car back and have a few things fixed on the car that I wasn’t happy about. After about a week, I was able to bring my car back down to drop off for a few days while the work was being done. I worked with their finance guy Keon. He lined me up a loaner to drive while they had my car. After about three days, the work was done and I went to pick my car up. I was very pleased with the outcome and they even fixed a few other things that we didn’t agree on but new I had questions about. They listened to me as a buyer and were willing to work with me. If you want to avoid big dealerships, they have a great inventory up nicer cars and are great to work with. I will shop with them again!

Damien Brown was super helpful on the phone and even more
Damien Brown was super helpful on the phone and even more so in person. This dealership has a huge inventory and he was very knowledgeable about all of the different cars available. There were no pushy sales tactics, and I never felt pressured. I would absolutely seek him out again if I were in the market to buy another vehicle.

Best car buying experience we have ever had.
Best car buying experience we have ever had. We drove from 6 hours away for this vehicle. Our salsman Ali was great. He sent us videos of the car and detailed pictures I requested before we went up there. I drove the SUV and loved it. Everything was great and we were done with the paperwork within the hour. They payment and interest all matched up. Our buying experience was absolutely great. Everything they told us and promised us was accurate and they even gave us a full tank of gas.

Wonderful Experience
Wonderful Experience" - Winneth This was my first purchase from CCT. My sales rep, Bernard Faulk, was fantastic to work with. He was very pleasant and very patient. I was satisfied with my purchase and the entire transaction with CCT went very smoothly. The manager and financial rep were also very pleasant. Great atmosphere in this dealership and they make you feel very welcome. Thank you Bernard for helping me choose a beautiful car, I know I will enjoy for years to come.
