Used GMC trucks for sale near Valley Stream, NY

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.

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.

My service advisor Andrew was very helpful and he explained to me about a repair that was covered under my warranty agreement but suggested I follow up with the original dealership to verify specifics about the type of warranty I have.

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. :)

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.

I don’t like phone calls, I prefer texting. I asked through their online form about a specific VIN and didn’t just get “yes, it’s available.” I got a full list - packages, history, and whether it could be reserved until the weekend. They actually waited for me even though interest was high.

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

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

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!

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.

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

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.

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.

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!

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

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!

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! 🚗💯

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.

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.

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.

Austin Rizzotti was very professional and made the purchase of our new auto a real pleasure. He never pressured us to make a sale. The experience was different from any other car buying we have had.

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

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?

Exceptional abundance of vehicles, i purchased both a work and person car here over the last 6 months and they have truly been awesome for me

Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

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 bought this truck new, mfg Mar 2012. It was still on the dealer lot Feb 2013, only 50 miles on it. A few minor repairs, had to replace the in dash entertainment unit due to burnt out bulbs, also having burnt out dash bulbs, headlight switch, drivers door switch panel / cluster. A few minor bugs during the first 30,000 but under warranty so not a cost issue. The " soft brake pedal " issue was resolved very early on by having the dealer replace the master cylinder. The only real problem is the " Passlock " security issue, once in a great while the truck will not start, somehow " it thinks " it has been tampered with / broken into, the small red car / lock dash light will be on, the indicator is on the right / bottom of the speed indicator. If you turn the key on, then off and wait 10 minuets then it starts fine, this has happened even while parked in the garage overnight, so I know for sure the vehicle has not been tampered with. This is a known GMC defect if you search on the internet and a forced recall should be done about it. The truck has a very nice and smooth ride, the 5 cylinder has plenty of power, highways and mountain roads are no issues at all, when I did replace the tires I purchased a premium 80,000 mile for a better and smooth ride, I still have the original shocks on it I now have 150000 miles on it, I follow the maintenance suggestions closely, well taken care of, I always get looks and complements where ever I go. The dealer I purchased from sucks ( Earnhart ) so I have to use another GMC dealer, and GM / GMC corporate was no help either, customer support sucks. Overall if you have one of these older Canyons or Colorados and you drive it normally and follow the maintenance you should get a long life from it, I use a premium oil and filter, change the air filter every 10,000 and keep up with the other fluids, I still have the original brakes on it, using a good / high cost premium wax every year and a light touch up every six months has kept it looking like new. The new and overhauled 2015 models seem nice, I may look at those if I ever need to replace this one.
