Used GMC cars for sale near Lake Grove, NY under $899,990

Donna and Jerry are true professionals. Always helpful, accommodating and informative. Everything is explained thoroughly prior to initiating any work. Highly recommend Riverhead Nissan. Gary C.

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?

Easily one of the smoothest & most trustworthy transactions I’ve ever experienced with a car purchase! Will never go anywhere else moving forward. Dejon N. was kind, knowledgeable, and very patient as I asked a ton of questions. Financing staff equally as lovely & incredibly helpful. Highly recommend this location! Thank you!

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!

we were in the market for a used car and Curran made it easy. My husband knows cars so he knew what needed to be done to make a used car safe and reliable. Curran offered all the safety and repair information up front. We didn't need to ask anything. The used car sales manager helped us throughout the process he was terrific as was the very thorough woman who assisted with our financing and all our paperwork. Everyone we dealt with that professional and we love our new used car.

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

great car has everything and then some. lots of seats and 2nd row heated is cool. it could use a little more under storage in the rear compartment and a cover

My guy Victor had me in and out in no time excellent experience! Go there

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

I thought was very professional and knowledgeable. Chad was my car salesman for my new 2023 Kia Forte. Chad was very professional and knowledgable. I will always reccomend Smithtown Kia to all of my friends.

Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.

I highly recommend Mike and Stamford Ford. Very friendly staff and got a good deal on the truck i bought. Tony the manager was nice as well - no games played at all. Nice dealership.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

if you go to this place ask for Oz... an absolute gentleman, and great salesrep ... very rare you find a man like that in the industry... overall 10/10 experience... never even asked me to write a review but my experience was too smooth not too

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

Rob and Joe were amazing and the car was in perfect condition. I drive 3.5 hours and they were very courteous and professional.

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 had a great experience at Generation Buick GMC with Joe Rossetti. He met all my needs, I will be recommending all of my friends.

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.

Great service from Zach. Very knowledgeable and thorough. Will definitely recommend him and Generation Buick GMC to my friends and family.

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.

I sold a pickup truck to AR Motorsport through Anthony. He was exceptionally nice and easy to deal with. He did not put pressure on me and made me feel very comfortable. Anthony treated me very well and offered a fair price. He was also kind enough to offer me an Uber ride home. Thank you Anthony!

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.

This is a wonderful family car. We raised our 4 children driving this vehicle. This is the 2nd Yukon XL we have owned. We have moved kids to college, towed hauls and driven cross country several times on family trips. LOVE this car!

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.

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 wrote a negative review of this dealership earlier but I am rescinding that one and revising my overall rating from 2 to 4 because I received a full refund of my deposit of $500 within 5 days of being unable to consummate a deal due to the high cost of shipping the 2006 Honda CRV I was interested buying. They were also quick to provide me photos of sections of the vehicle I wanted to check.

My favorite car I have ever owned. I've had cars, trucks and a couple of small suv type vehicles. I thought it would feel like a big blazer. And boy oh boy was I wrong. I bought it ar 180,000 miles and it drives like a dream. All the power I could ever ask for. A bigger engine than my camaro had and almost as fast. My kids love it, I love it the wife hates the mpg but if we have a snow storm we take the denali, when we have the 4 kids me and mom and we can still fit another adult and any and all luggage. What is there to complain about. It's reliable and when you expect the instrument cluster panel to be wonky from bad wiring. Well it's nothing that stops me from getting where I want to go everytime. I love the vehicle and hope to keep it for a very long time.

Shania was well informed when assisting me to purchase my 2023 outlander PHEV. Shania went over the vehicle step by step and made sure I was comfortable being a first time Hybrid owner. Thank you again Shania

John McCoy was a great salesman! He was honest, communicated well, and applied no pressure to make a decision. This dealership was the only one on Long Island that was willing to negotiate a deal on the car I purchased. Every other dealer said that they could not lower the price of the car even $1. This is the third vehicle that I purchased or leased from this dealership and I will return when I am ready for my next vehicle.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Great deal. No gimmicks or nonsense. Thanks Sean for making it such a smooth transaction. When it?s time to for another purchase I will certainly be back.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

I was concerned about going to an out of state dealership, but I was impressed with your high customer service ratings from customers. I felt they were very professional and while pushing us to make a decision, they weren't obnoxious about it. In the end I thought they gave us a fair deal and we love the SUV. I would have no problem making the trip to Massapequa to buy another car.

We recently purchased a 2017 Toyota Highlander from Toyota of Massapequa, and the experience was absolutely outstanding from start to finish! From the moment we walked in, our sales representative Nomaan made us feel comfortable and respected. He was incredibly knowledgeable, attentive, and, most importantly, genuine. We initially came in to look at a specific car, but ended up spotting a few others that were out of our price range. Rather than pushing us toward the more expensive options, Nomaan had an honest conversation with us about what mattered most to us, our budget. He truly listened and helped guide us to the best fit without any pressure. My husband had a question about the brakes, and the team at Toyota of Massapequa didn’t hesitate, they immediately reinspected the vehicle and even resurfaced and replaced the brake pads. That level of transparency and care meant a lot to us. As Nomaan said, “First is the best”, and in our case, the first car we saw in person ended up being the one. We are thrilled with our decision and love our new Highlander! We also worked with George, our financing associate, who did a fantastic job laying everything out clearly and ensuring our monthly payments stayed within budget. Both Nomaan and George were extremely warm and welcoming, it honestly felt like talking with family. Despite arriving close to closing time, we were never rushed, and they both took their time with us like we were their only customers. We’re beyond happy with our purchase and the overall experience. Five stars all the way, we would absolutely recommend Toyota of Massapequa (and especially Nomaan and George) to anyone looking for a car!

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.
