Used GMC Sierra 1500 SLE for sale near Dunstable, MA

I had an excellent experience at McGovern GMC Westborough. Ben, my salesman, was fantastic—he was helpful, never pushy, and kept great communication throughout the process. He really listened to what I wanted, respected my budget, and even took the time to get to know me while sharing a bit about himself, which made the experience feel personal and comfortable. Omar in finance was just as great—super friendly, honest, and transparent about everything. The dealership itself was clean, well-maintained, and in a very convenient location. Overall, the entire process was stress-free and enjoyable. I’d highly recommend them!

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

It's a better experience, all the more so that I represent your brand and a team that is doing pretty well

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

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

I was looking for a used Jeep and after looking around, this dealership really took care of their used cars. The jeep that I purchased from here was well maintained and clean! There were some small parts missing from the vehicle and when I purchased the vehicle, the dealer ordered the missing parts for me for no extra cost. Overall experience was great and would highly recommend.

We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

Beautiful showroom gorgeous used cars. I was taken aback by how awesome the service is.

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!

Top notch dealership. Made buying our son his first car a very simple process. Friendly, helpful staff. If you're looking for a quality used car this is your place.

I really like my nw, to me, 2015 GMC Sierra Denali. The salesman, Terrance Lin was very efficient, helpful and courteous. Thank you very much.

I am very happy with the SUV I bought from Truck World. Everyone was very welcoming and helpful. Brian made the financing process really easy and they made sure it was cleaned and ready for pick up

Bought this truck used,I love the comfort. I used to have a ranger.I can fit my plywood in the bed and close it.It is a long bed.My 12 foot jon boat fits good,.better than the ranger and more comfortable

Grieco is an easy-going no pressure dealer. Justice are sales rep is a really nice and friend guy and was a big help purchasing a BMW my son wanted. Thanks for all your help Justice.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Brett, Ron, and Karen were awesome. They made the whole process go very smoothly. I'd recommend them to anyone.

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Excellent salesman Scott. Dealership impeccable. Everyone professional and courteous. Explained every detail of buying process. Finance staff Kendra extremely professional and explained every process of leading my vehicle

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 couldn’t be happier with my experience at Richards Motorcars, mainly due to the GM I worked with, Joe, who was great. He was prompt and very easy to communicate with over the phone and via texts. He answered a lot of the questions I had before I even made it to the dealership. I made an appointment, checked out the car and was able to do the test drive, fill out all the paperwork, and complete the purchase in a little over an hour. I couldn’t recommend the dealership more.

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.

If you want a dealer experience where you and your time is respected come to Ford of Londonderry. Ford and Ford of Londonderry provided me with an exceptional experience. One of the best dealer sales interactions I've ever had. I scheduled an appointment online for a test drive and the sales associate was there and available for me to interact with on time. She had good knowledge of the vehicle and answered many of my EV and car questions. The test drive was good and thorough and we were able to explore the features. After the test drive they provided some pricing and I went on my way. I had a lot of follow up questions and they were able to get those answered as well. I proposed some revised sales numbers and Ford of Londonderry was able to make it work. I went in to finish the deal and it was a quick and easy process. No pushing of addons or games with sales numbers or any other shenanigans. They walked me through some of the detailed features, helped me set up my phone and vehicle. A VERY GOOD experience and I am very happy with the interactions and the deal provided for my new Ford! Good work on all fronts.

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!

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

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.

Fantastic customer service. Tristan was great. Greg and even the GM, Armando. Highly recommend working with them. Last minute, we found a large scratch and they were actually embarrassed it had been missed. Jumped on fixing it and offered to deliver it to us when done. WOW factor!

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

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

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.
