Used GMC trucks for sale near Freeport, NY

Tim, the Service Department Manager, provided excellent services (from initial phone quote to drop off to cost adjustments and final pick up experiences).

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. :)

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!

Ronny Terraferma was amazing. Treated myself and my daughter like family. He was honest and professional throughout the entire process I will definitely will return for my next car!

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!

It has been a pleasure working alongside Carlos at stream auto. He and his team made it an easy smooth transition for me to leave there with a great car and a smile on my face thanks again team five stars to Carlos

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.

Wow what a complete difference in professional service from Generation GMC in Sayville compared from King O'Rourke in Smithtown. Service department is amazing. They send you a video from the mechanic going over all the concerns that you have any what they found. I was constantly being told my oul leak was a seel. Thanks to Generation GMC they took the time to find the real cause and it's going to take a week to fix. Thank God had the issues at King O'Rourke otherwise I wouldn't have found an amazing dealership. Especially Thanks to Maria for keeping me updated.

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.

Very kind helpful and make sure you come out with a car. The most I like about dealership is there workers

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

Fast great service . Courteous staff. Easy to make appointment. Kept me updated the entire time vehicle was in shop. Highly recommend. Definitely recommend to family and friends

I WENT WITH MY DAUGHTER TO TEST DRIVE A NEW RAV4 AND DEALT WITH KARTIK GULATI.HE WAS VERY PROFESSIONAL,HELPFUL AND POLITE.AFTER TALKING WITH K.G.I BOUGHT A RAV4.I AM IMPRESSED WITH K.G.AND EXPERIENCE AT DEALERSHIP

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.

Rodrigo is great sales person i buy 3 cars from them good dealer no hiding fees

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...

Tom Cali is an excellent salesman. He is so professional, patient and helpful. We went to buy a pre-owned Lincoln Nautilus or Aviator and he was so patient with us and just made the whole experience a Real Pleasure. We will be recommending everyone we know to go to Bright Bay Lincoln and that is where all of our future purchase will be. Also, Prescott in finance was honest, caring and wonderful too. FANTASTIC EXPERIENCE ! ! !

The absolute best dealer I’ve been to by far in my search ! Low prices clean cars and low interest rate!!! Will refer my cousin to you as he’s looking to buy next week! Thanks Euro A++

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

I purchased a 2026 Equinox from Mr Tom LoBue, who was professional & courteous through the process & made sure I got the vehicle that I wanted. Thank you.

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.

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 !

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 purchased a 2023 BMW X5 from Island Auto Group, and the experience was outstanding from start to finish. I’ve bought and leased several vehicles over the years, and this was easily one of the smoothest, most transparent car-buying processes I’ve had. From the moment I arrived, the team was professional, knowledgeable, and respectful of my time. There was no pressure, no games, and no hidden fees, which is something I really appreciated. They walked me through the details of the BMW X5, answered all my questions clearly, and made sure I understood every option before moving forward. The pricing was fair and competitive, and they were upfront about everything — trade-in value, financing, and next steps. The vehicle itself was in excellent condition, exactly as advertised, and the delivery process was seamless. What really stood out was the customer-first approach. It felt like they genuinely wanted to earn my business, not just close a deal. The entire process was efficient, professional, and stress-free. If you’re looking to buy a pre-owned luxury vehicle like a BMW X5, or honestly any car, I highly recommend Island Auto Group. They made what can be a complicated process feel easy and straightforward. I would absolutely buy from them again.

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.

I had the pleasure of working with Jesse. He was very professional and extremely patient. He took the time to answer my questions without Casting judgment are thinking that any question was not important. He was able to relate well and made me feel comfortable and at home. I would definitely recommend this dealership and especially Jesse to family and friends. I had visited other dealerships prior to Metro Honda and did not feel as if I was taken seriously. We are extremely happy with our purchase.

I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

Great Experience!!! Smooth process, Lorena was awesome, excellent value, stress free pickup, highly recommend to go see Lorena.

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

Great Service!!! Smooth transaction and very helpful staff. Renny T. was our salesman; he helped us with leasing our car. I would recommend this dealership and Renny as the salesman. Definitely coming back here again!

Bought this 2016 GMC Canyon (4cyl) at car max in 2017 . It was part of a commercial fleet and was well taken care of and low mileage . I’ve only have had one problem and that was in the engine cooling system where I had to replace two hoses and a goose neck . While repairing that I noticed an oil leak around the valve cover so I replaced the gasket . It was under warranty still ( just happened in Jan 2024 ) . I could have repaired it myself but who wants to get all dirty when it can be repaired by GMC at little or no cost to me. It still has 6 months remaining on warranty ( I did purchase from CarMax) hoping it does not need any further repairs . It is 8 years old and according to its records this is the first repair other than natural repair items that had ever been needed . It rides well pulls my utility trailer fully loaded just fine . I also have a 2000 Ranger that I had to replace the tranny on when it was just a few years old . It has never needed any other work. I believe the GMC will last me for years to come . But you never know so I will be buying another after market warranty on it when the time comes . I’ve already added that to a 2015 vehicle I own who’s warranty had expired . I’m a old school mechanic I can repair olde vehicles easily ( compared to todays ) I’m also a former Turbo Prop Mechanic from the Air Force and worked those motors for almost 29 years . I had worked on Piston Air Craft Motors for a few years before the change . A lot like a car piston motor in many ways . Two kinds of piston motors on Air Craft . Line a cars block or a receptacating motor( Round) . Very easy to trouble shoot vs Turbo Prop. Just letting you know that I have experience as a mechanic and know a real problem vehicle when I see one . Would buy a GMC canyon again or maybe go larger due to my new 42 foot long Camper I have rec bought .

We’ve been buying cars here for the last 6 years. My go to place to purchase all my cars. Everyone is friendly.

I bought my gmc canyon used with 29,300 miles on the odometer. It has the 2.8 ltr I-4 turbo diesel engine. I'm towing a 5,000 lb travel coach. First thousand miles was today. The small engine gets for me astounding fuel milage. Towing the coach i averaged 22. 8 mpg on a trip to the Eastern Sierras. 368 ft lbs of torque is more than enough to haul the trailer to 10,000 + ft elevation. Just be patient and use the torque to tow up a mountain. The fit and finish is excellent, the blue metallic paint turns heads. After 3 yrs a good waxing had it looking showroom new. This is my first gmc ever. If it holds up and runs 300,000 miles like the sales rep stated it's capable of doing. I'll let you know. The one down side is the emissions on the engine can cause reliability issues. Advice i found on a forum says use a good quality injection cleaner in every fill up . Every fill up for the life of the truck. They are capable 300,000 and higher if we'll cared for.
