Used GMC Sierra 2500 Denali for sale near Durham, NH

Seth was a pleasure to deal with and secured a deal in minutes, best experience I've had buying a new vehicle. I will definitely pass the great experience I had with others.

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.

Arrived a day early for my appointment, took me in and did service in an hour as promised

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.

Justin, one of the service writers, is the best to deal with in the area!! He is always trying to help me with any problems I may have and always goes above and beyond for his customers ! He is the reason I always go back for any service my Ford Raptor may need , Thanks, AK

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.

Great no haggle price and trade best buying experience I’ve ever had buying new vehicle and this is my 30th!

Fast friendly, and didn?t try to talk me into anything I didn?t want! Thorough as well! Such a great experience! This was my second purchase from Banks and I?ll likely never go anywhere else!

this truck fits my needs better than the other 2500 models. Its hauling and towing performance along with its many people comforts will satisfy us for a long time to come.

I had a very good experience super easy sales process. The salesman was a no pressure great guy as was the Finance department. Thank you

I recommend Banks and especially our sales person Kevin Mathis! He was knowledgeable, personable, and efficient. We also had a great experience with his manager and finance manager. Overall, I can’t say enough good things about the experience and I love my Denali. You are shopping for a new vehicle or use vehicle. I highly recommend banks and Kevin Mathis

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 am a new and satisfied customer. Being a woman with little to no car knowledge, they provided 100% accurate info. Not the case with me in the past. They certainly restored my trust in car dealers and mechanics. They didn't add unnecessary work and only did what was needed. I'd recommend my closest friends.

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.

Got a truck from them bought running boards for the pickup but couldn’t put them on cuz running boards were rotted so called Tim’s an they said bring the truck down an fixed the issue thank you

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

I've not been to the lot yet so can't rate anything but customer service. And their customer service is A . By far, the nicest and most honest dealership I've ever spoken to.

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 like to thank Tim Jr and the service department for helping me with tires for my truck. As always was greeted with great customer service and the service tech did a great job . Thanks again Tim and team great experience every time.

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!

I recently brought my car in for some emergency service. I had to have multiple items repaired or replaced. The staff informed me every step of the way, calling with updates and answering any questions I had. The service team was friendly, knowledgeable and able to explain things to me in terms I would understand. Ben, Will and Ryan were all a pleasure to work with. They've got a great team in the service department. And the best news is that my car left in better shape than it arrived :)

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.

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!

IT WAS SO NICE FOR THE SECOND TIME TO DEAL WITH CHRIS ANDERSON. HIS KNOWLEDGE OF VEHICLES HE SELLS IS OUTSTANDING EVERYONE I TALK TO DO THERE JOB WELL.NO BS. THE BEST EXPERIENCE I EVER HAD AT A DEALER

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.

I was in for an oil change and the services were prompt and ready before estimated time

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!
