Used GMC Sierra 2500 Denali for sale near Cockrell Hill, TX

The entire sales staff from salesman (Kenneth) to the new car director had a hand in making sure all my emails and questions were answered immediately. You can see the shear number of people below that were involved happily. I was never told the line "we just need you to come in..." once. Everything was done my way, on my terms and I never heard the "lemme go talk to my manager" lunacy you hear everywhere else. All I was told was "sit and relax and I'll take care of that for you." I've never seen a dealership operate this way. One of the smoothest purchases I've ever had. Well done.

My visit was for an Oil Change (Works) and the service was outstanding. The Service reps were Professional, Knowledgeable and kind. I would recommend Autonation to anyone looking for quality service or a used and new car.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Marco is super good and he handled my need properly. He is quite soft spoken and understand the need before jumping the showing the cars. As per the selling price point, you guys are best in DFW area.

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

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.

Dennis made the buying process very easy and I was able to drive away with the truck I was looking for in no time! Highly recommend

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty 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.

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

Nathan always gets us in and out with great service! Quick oil change, tire rotation, and air filter were done. This is the only place to go!

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

I have bought several trucks from Kevin, they are my go to place for a good deal. Can't recommend them enough. They even got me a great rate on financing.

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

They have nice cars and are easy to work with. I recommend them for cars that have a bit of personality for sure.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Got in touch with me very quickly when I messaged. Very easy to work with and the truck I bought was priced to move. Easy buy and great experience overall!

I drove to Crown Buick GMC after making an appointment with Tammy Wagner. She was a new sales person. Tammy is very patient. She enjoys people and made me feel comfortable. I had alot of questions about my new All Terrain Truck. When she didn't know the answer- she was honest. (thats important to me) They , Tammy Wagner and Mike Mathis her manager sold me the truck of my dreams. I plan to be a life long customer with Tammy Wagner at Crown Buick

Several sales personal where informative and knowledgeable in customer service. I didn’t purchase a vehicle but will give Vanguard the first choice at sales.

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.

Steve was excellent to work with unfortunately @ this time I didn't buy the car thanks George

Just the truck I was dreaming. Auto world experience is great on product knowledge high recommend 2500 Hdz Denali truck you won’t regretted price product and drive experience

Could never buy another truck after owning this. I'm only getting rid of it cause I ordered a 2021. Hands down, this is the best of the best!!

By far the most painless car buying experience by far!! Nathan was on his game in sales, got me to the perfect truck first shot! Colby the SM was fantastic! Efficient and knowledgeable quick to share small print details and worked hard to get my interest rate lowered! Hats off to you guys! Thank you! Will highly recommend to anyone i know shipping!

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!

Great buying experience, much better than other dealerships for buying a vehicle. They didn't force us to add an extended warranty or other typical dealership nonsense.

I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Great service and overall just great experience. I highly recommend to anyone looking for a vehicle

Thank you Robert and Don for your professionalism in attending to my car services I appreciate your attention to my car?s needs Exceptional customer service

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!

Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.
