Used GMC Sierra 1500 Denali for sale near Lexington, MA

We purchased a Mazda CX-50 from Tulley Mazda in Nashua NH. We had a problem with the new vehicle and had to bring it to the dealer several times until the tech finally found the problem in a wire harness under the dashboard. We were given a loner each time we had to leave the car . Alex and their team are the best. They are professional in the way they do business. Have purchased cars from other dealers and never had such great service .

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

Great old fashioned way of doing business. Professional, smooth, non-rushed atmosphere. Mr. Paul Macchi is a great, concientious employee. I thank him for his courtesies and cordiality.

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!

Very personable guys , absolutely no pressure sale , Leo provided us detail on the car which was ready for us to test drive when we arrived . Great synergy between Leo in sales and Joe- finance . No nonsense auto group .

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.

One of the best car buying experiences we have had. Brittany was excellent, knowledgeable, and gave the best demo with attention to every detail, and certainly was not pushy (which is a criticism I have had with other dealerships). An all around enjoyable experience....wonderful interactions with the sales manager, finance manager and Jack Madden. Beautiful new service facility with exceptionally friendly staff. We will be back.

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!

Everyone at Tulley was great! They even took my old car as a trade and gave me a great deal.

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!

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Matt is Excellent. Outstanding customer service he is knowledgeable and quick and made the buying process a breaze. He went out of his way to make our experience the best it could be and stayed late to make sure my Wife could take hers home same day. I bought 2 cars in two separate trips on Saturday in the time it would take to buy one at other dealerships. This is my 4th car from AutoMax and have never had an issue with any of the vehicles or the experience. This is the place to go and I will be buying my next car there and asking for Matt.

Fantastic Service and Sales department. My family and I jae purchased mulitple GM's and use Tulley Buick GMC's service department exclusively. Thank you Tulley.

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

Great guys. All very helpful. Got me exactly what I wanted. Thanks again Shea, John, and Omar. See those guys 👀

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 purchased a used 2012 CTS in July and I must say it was one of the best dealerships I have ever dealt with. From Hank Landry in Sales to Brian and Andrew in Service they a truly a pleasure to deal with. I would recommend this dealership to anyone, you will not go wrong. I thought the pricing was fair and the car was in outstanding condition, it was obvious that it had been completely serviced and ready to go. I will not hesitate to buy from Long Cadillac again in the future,

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

If I could give more stars I would I have never been comfortable dealing with dealerships and car salespeople in general . I did a lot of searching at different places for my new vehicle .I found what I was looking for at McGovern Westborough .Here I met Ben Fasano . I was pleasantly surprised .He was extremely helpful in not only finding what I wanted with absolutely no pressure. But Even after I purchased the vehicle he has been helpful with the registration and all that goes with putting it on the road. Not only Ben but all the people at this dealership made me comfortable with purchasing a vehicle here even though it’s 30 miles from home. So far so good !!

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.

Brought my 2011 GMC 1500 in for service for routine maintenance and the team did a great job as usual. I've been servicing my truck here since day 1. Thank you Dustin and team.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Love my Sierra AT4, the team there was great! 5 stars! Only wish is, that I would have done this sooner.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Very pleased with my purchase. No pressure during the process. Had the truck I was looking at as advertised.

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. ??????????????????????????????????????????? ?????????????

Great customer service - easy to schedule appointment and even provides me with a ride back to my office!!

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

I had a fabulous experience purchasing my Sierra. There is NO pressure which is a breath of fresh air. They are extremely knowledgeable, kind, trustworthy, and you will feel very confident in buying from them. I go there for service too and everyone remembers who you are and they come up to you to say hello. If I could give them more stars I would. This dealer is exquisite.
