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!

The salesman, Joe Rodriguez, was very helpful and informative. I had no problem with communication. Everything was handled very Well. Everybody there was very professional. financing was excellent And I would definitely recommend this dealership. to anybody that was looking for a vehicle. Keep up the good work
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Overall, Vandergriff Chevrolet service dept.
Overall, Vandergriff Chevrolet service dept. did an excellent job on my repair. With an extended warranty, the repairs cost nothing. But if I do critique anything, is the trying to get me to spend $1,200 in new battery cables. There was nothing wrong with them.
Best truck we have owned!
Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

After many hours of learning current market values and
After many hours of learning current market values and contacting many dealerships, Classic Chevrolet in the first phone conversation revealed no fixed or high pressure add ons - that was enough for me. Dealing with Classic Chevrolet was about as straightforward as you can get in dealing with any car dealership. Vehicle was available and as described, no dealer add ons (which seems to be a major issue in Internet pricing), and no high pressure sales. Just the typical unfun price negotiation at the end which I have 100% experienced in my every car buying experience. As a totally different experience, cars.com should deny service to Autosaavy and Car Revolution. One would be insane to attempt a purchase after reading their reviews. They do harm to the Internet buying 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.

Working with Ethan on my 1st ever online purchase
Working with Ethan on my 1st ever online purchase - was the 1st experience everyone wants! He was efficient with communications, but never pushy. He was flexible and open to any questions, while walking me through the process! Friendly, knowledgeable, and great to work with. The financing process with David's help was a breeze! The process was time efficient and pretty flawless. He was on point with communication and very knowledgeable. Still loving my new car 2 months later- it exactly what I wanted and drives like a dream!!!
