I went in and they worked with me quickly on the truck
I went in and they worked with me quickly on the truck that I was looking at and addressed all of the issues/concerns that I had immediately. I highly recommend this place if you’re looking for a pick up.
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

I have purchased cars from Sewell in the past and once
I have purchased cars from Sewell in the past and once again, their service and inventory is SUPERIOR! We are so happy with our vehicle and the overall experience!
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Buying a car from Clay Cooley was one of the best
Buying a car from Clay Cooley was one of the best experiences I’ve had. The car was exactly what I was looking for. Communication was easy, and they made sure everything was ready for a smooth, quick sale. Super friendly and honest. I would definitely buy from Hector and Trevor again or recommend to anyone looking for a good deal on a car!
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Very smooth, efficient, and courteous.
Very smooth, efficient, and courteous. Iliana was amazing!!! Will definitely be back in the future. Very professional & knowledgeable!
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Carl Miller answered questions I forgot to ask.
Carl Miller answered questions I forgot to ask. Straightforward and not pushy, very refreshing. I would buy from them again. This was an out-of-town purchase and it was a piece of cake to get the job done.

Best Car Buying Experience Ever!!
Jose the Sales Manager listened to what I wanted and found the vehicle at another dealership and brought it over. Briana in Sales showed me all the features and explained how everything works. She even helped me get the app set up on my phone. David in Finance was so friendly and made the process easy. I have told all my friends how nice everybody was to me and this was really a no-stress day. I love them. I wish I could buy a new vehicle every year so I can go back over and over.

Vanessa and one of the managers ( can't recall his name)
Vanessa and one of the managers ( can't recall his name) were extremely helpful. There was some confusion about the scheduled maintenance and what was covered and what wasn't. I explained to Vanessa and the manager what had been communicated to me by Graff Chevy & Brandon at Classic...they reviewed everything and completed the service based on what was communicated to me and sorted out the other communication internally. Additionally the service was completed in half the time I expected. Previously, I had a challenging experience with the body shop so Classic was not my first choice for this work, but I decided to give you a other try and it worked out far better. I'm pleased with this service and thanks again to Vanessa and the service manager she engaged to assist.
