Used GMC Sierra 1500 Denali for sale near Portsmouth, NH

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

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Bob and Derek were very nice and helpful! Easiest buying process and customer service was excellent!

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

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.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

I bought a used 2015 CX-5 in 2015 from Seacoast. From start to finish, the buying process was great. Absolutely no high-pressure sales tactics. No tricks or gimmicks. I got a fair price for my trade. And a good price on the CX-5. Salesman Ryan McGuire was patient and knowledgeable. The service dept was also top-notch. They took care of a bug in the entertainment system right away and made sure the car was perfect before handing me the keys. I would highly recommend Seacoast Mazda.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

I recently purchased my Jeep Cherokee here and had a great experience! All of my concerns were addressed without hesitation. Everyone was extremely professional, patient, and kind. I highly recommend this dealership to everyone.

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

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 have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

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 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!

Awesome I was very pleased. They called me and told me they had a pickup I might be interested in so I went over and it was very close to what I was looking for so they give me a good price and I bought it.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

I purchased a pre-owned certified CX-5 in great condition which I absolutely love to drive. Ryan McGuire helped me to realize all this vehicle had to offer as I spend a great deal of time on the road. He was truly the bright spot of this purchase (besides the car)! I always dread the actual sales process (haggling over trade-in price, the "real" sales price of the new vehicle, etc.) and it still was not the most enjoyable experience despite excellent credit and a very clean trade-in. However, the service department, particularly Joe Smith, provides excellent service for regular maintenance (no need for repairs yet). As for the facility itself I hope the employees one day have the new building they deserve!

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

We just purchased a 2024 GMC. Bob Corey and Nick Pridham were amazing in helping us through the buying process. Bob was an amazing sales man.i Dont like the pressure most car dealers put on the customer but we felt none of that with Bob. Thank you so much for making our truck buying wonderful.

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

After a not so great experience (from another dealership), I made sure I did my homework and knew exactly what I wanted...After talking to Rob H a few times to check out the inventory and ask questions, he was very professional and never made me feel pressured into buying a car. He answered all my questions and gave me a few options and told me to call when I was ready. When stopping in one night to finally make my decision, from the moment the car was brought out for my test drive, to the time I drove it off the lot, it was THE MOST BEST CAR BUYING EXPERIANCE EVER... I want to thank everyone for staying late to make sure the paper work was done so I could take it home that same night..!!!! I will deff be a customer again and thank you for making me part of the mazda family..!!!

small dealership, low pressure sales, great prices, first visit and drove my car of the lot.

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Everyone at this dealership was friendly and helpful. Dealership was immaculately clean. they went the extra mile to make us feel welcome and comfortable. Great experience. Thank You, Bob & Colleen Kilpatrick

Responsive and honest, both sales and service! Bought my first Mazda here, was very satisfied with the sales process (low key, honest, good inventory). Have been using them for maintenance since, and can truly say they have been the most accessible and approachable car company I have ever used.

I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.

Kristy and Paul are great to work with and are very accommodating. I know I will receive great service at a great price when I bring my truck in.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

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