Used GMC trucks for sale near Valley Stream, NY

Dealing with Luke and Ryan was a pleasure.. No pressure and very professional. I would buy from this dealership again.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

I used the service department on my Lexus rx 350 and Diego was great. Very accommodating. They replaced my wipers and now they work great. Diego was really on top of things. He arranged for me to even get a loaner car while they were servicing my car.

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.

Honest dealership and car tech 's. The only problem is that this is a small dealership and they need more help in getting the back log of cars needing repairs moving faster. They should also have Saturday appointments in which they do not to do oil changed and minor repairs. Most dealerships have Saturday appointments but this dealership don't

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.

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.

Overall Great Experience from start to finish. Elder and Ralphie communicated with us every step of the way and made the process of buying our car seamlessly. They both were friendly and professional. I would definitely recommend Stream Auto outlet in Islip if you’re looking for a great selection and team. Mark & Jenny

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!

Their website helped when I was hunting for a specific Envision color. I set filters and an alert, and as soon as the right trim showed up, I got an email.

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

Excellent dealership I was in and out quick with my daughters new c300. They got me approved even with my itin at a very low rate. Clean cars inside for sure go check them out !!

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.

The best used car purchase I’ve ever had. It was easy, simple, and straight forward.

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.

Peter was the best. I have over 50 automobile purchases in my life time. And this was the easiest and best one yet. Thanks again

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!

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.

Very willing to work with me and stayed in touch through the whole experience thank you

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

Best used car purchase experience I have ever dealt with. They were patient, helpful and did everything to make sure I was comfortable with my purchase! Highly recommend Dan and team

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.

Joe was absolutely brilliant from start to finish it took him a total of 25 mins to get me in and out with a 2024 ford f-150 w 23k miles these people are fast efficient and give you the best deal off anything you need definitely recommend especially Joe he made sure everything was nicely cleaned and explained ask for Joe when you go

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.

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!

I didn't have to do anything because they took care of all the paperwork. The process was easy, well-organized, and stress-free, which made the whole thing straightforward and convenient.

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

Island Auto Group is the place for 🚗 Let me share my first car buying experience in New York. As someone with zero prior knowledge of how dealerships work, it was incredibly challenging and stressful at first. For over a month, I hunted for a reliable, low-mileage car with excellent safety features, low maintenance, and something within my budget. I ultimately decided between a Subaru Crosstrek or Mazda CX-5. I checked online sites like Cars.com, Carfax, and CarGurus, visited around 10 dealerships (both independent lots and franchises), made tons of phone calls, and even explored Carvana and CarMax. Too many places baited me with low online prices, only to pile on thousands in hidden fees once I showed up—things like mandatory down payments, wear-and-tear charges, inspection fees, and dealership add-ons. But from this experience, I learned a lot about how dealerships really work and gained some valuable knowledge: never fully trust the prices posted online without confirming the true out-the-door cost in person. After five frustrating in-person visits, I was ready to give up on traditional dealerships and just overpay at CarMax to avoid the headaches. That’s when I spotted a listing on Cars.com from Island Subaru. The vehicle photos clearly stated “No hidden fees, no extra fees – fully transparent OTD price.” Skeptical after so many bad experiences, I decided to try one last time and walked in without an appointment or even a phone call. Right away, I met sales representative Christopher Chavous (everyone calls him Chris). He was patient, professional, and didn’t bombard me with unnecessary questions or personal info. He showed me the Crosstrek I was interested in, sat with me for two detailed test drives, and explained all the features thoroughly. The standout moment? Chris gave me the true out-the-door price immediately—no games, no surprises, exactly matching the online listing with zero hidden fees. In an industry full of tricks, this level of honesty instantly built trust, which is everything when buying a car. After some fair negotiation, the manager approved a solid discount, and we sealed the deal that same day. Since it was Saturday and close to closing (they couldn’t finish the NY inspection), they went the extra mile and loaned me a brand-new Subaru Crosstrek to drive until Monday when my car was ready. Finance manager Yuri Miyakawa handled the paperwork smoothly, got me a great rate, and made everything straightforward. But Chris truly went above and beyond—he guided me through the entire purchase process and even helped set up my first car insurance. The initial quotes were sky-high for a new driver, but Chris personally called the insurance company, advocated on my behalf, and somehow got my rate reduced to half the original quote! That kind of dedication is rare. The whole team—the manager, Yuri, Chris, and the rest of the staff—was genuinely helpful and made me feel valued. I drove home in my Certified Pre-Owned Subaru Crosstrek Limited with just 9k miles, at the exact negotiated price, with all documents perfect, a full tank of gas, a fresh car wash, and three free oil changes for the first year. Island Subaru transformed a potentially nightmare first-time buying experience into something positive and memorable. Their transparency, honesty, and outstanding customer service set them apart. I’ll definitely recommend them to friends and family, and I’ll be back for my next car. Thank you, Island Subaru team—especially Chris for your incredible support throughout! 🚗💯

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.

Mikey helped with purchase of BMW. I'm thankful for his professionalism and patience. I Recommend him and BM Motors

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

Came in for service this morning I was out of n under an hour Dean ,Michael,Danny,andJon always fast friendly and courteous have been coming there for years always exemplary service a credit to East Hills Jeep

Missing a few things that could really make it better. Homelink for garage door isn’t offered? Doesn’t come with a receiver type hitch however what does comes with it is almost the same amount of steel. The phone charger doesn’t work quite right and they know it.

Good service, nice treatment, great car selection. Overall experience was good. will come back again

2019 Canyon Denali. All sorts of bells and whistles, several that I don't really need. Biggest complaint: no memory seats and no Homelink garage opener. Ridiculous. What accountant made that decision?

I had an outstanding experience with Belford Motor Company and can’t recommend them enough. I worked primarily with Mark and also with Dan, and the entire process was seamless from start to finish. Because the dealership is a bit of a distance from my home, I asked if most of the paperwork and details could be handled via email so that when I arrived, I could simply sign and drive. They accommodated this without hesitation — from the initial deposit through the final paperwork. When I came in, everything was exactly as promised. I took a quick test drive, signed the necessary paperwork and then happily drove it home. The process was incredibly efficient and respectful of my time. What stood out most was the friendliness, professionalism, and competence of the entire team. They truly stand behind the vehicles they sell, which is evident in the dealer warranty they provide. I was also impressed by their unexpectedly large inventory of high-quality vehicles. Thank you again to the Belford Motors team for your excellent service and making this such an easy and positive experience!

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!
