Used GMC Sierra 1500 trucks for sale near Mendham, NJ

Great experience. My sales rep was very knowledgeable, helpful, and patient the whole time. He guided me through checking out the cars I wanted to see without any rush or pressure. This dealership is worth checking out.

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. :)

Had work done on my Jeep Grand Cherokee with Nielson. Professional and polite service. Work was done complete. Special thanks to Michael Andolina for his Professional and courteous service. I will continue to do business at Nielsen

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Chris was the best to deal with; quick and to the point would definitely buy another vehicle from him. Young boy but knows his profession.

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!

William, my service representative, was extremely helpful. The tire sensor went bad and the technician was able to replace it while I waited instead of coming back. The staff at Malouf is always very helpful and professional.

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 !

Solid dealership. If you know cars, you’ll understand why it’s worth stopping here instead of driving around ten places.

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.

Tristan is the man!!!! We love our new Jeep it’s so clean and so nice for a 2021 we got a Jeep compass he personally delivered it with a pink bow in memory of our 15th month old daughter (which was her favorite color) and flowers. He’s personal and professional. Easy to work with and gets the best deals and insurance rate topped it FULL coverage through geico. I was shocked at my insurance rate. Wow we love you Tristan keep up the hard work and dedication to your customers.

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 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.

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.

What a nice buying experience. Going to a dealership is often like going to the dentist, but salesman Michael Caragher made it as pleasant experience as buying a car can be. No hassle, not pushy, ez going and professional. Terry T. Chicago

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.

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 bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Great dealership, tremendous ownership (McGuires).... absolutely terrific salesperson (Sarah Baker). Honest, straightforward transaction. I highly recommend McGuire Buick GMC to anyone in the market for a new car.

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Was greeted with a smile by Mo as soon as we walked in. Told him the car we'd like to look at, he gave us a brief overview of it and handed us the keys for us to check it out. Straightforward numbers right from the start and no hidden fees of any kind. Purchase was completed efficiently and quickly and we are very pleased with our purchase and the experience there today! Simple, honest transaction.

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!

I was looking for a great used car for many months. I couldn't find the right match with price, quality and financing. I then stumbled onto Carsrus in Rockaway, New Jersey and found the perfect car for my family. Clint and John are the best out there. They new I wanted the car and they did everything they could to make sure it was mine. I drove away in my perfect car within hours. It was a great fulfilling experience to deal with them and I would recommend them to anyone in the market for a great used car.

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

My experience with Acme Nissan has been truly exceptional! This is the 4th vehicle I obtained at Acme Nissan with each experience better than the last. I had waited for my car to arrive as I wanted a specific model. From the moment I entered the showroom, I was promptly greeted and felt less stressed as the receptionist was very friendly as was everyone I had encountered. A very special thank you to Jake Jaskowski for going above and beyond to ensure I got the car I wanted! This is one of the main reasons I decide to continuously do business with Acme Nissan as the exact car was readily available at another Nissan dealership where I could easily picked it up. Dennis Silowka is a great sales consultant as he worked hard to ensure I knew about all the features of my new 2024 Nissan Altima VC-Turbo 2.0SR. He provided me on-demand access to very important features using the showroom tablet and answered all questions I asked. I completely my paperwork with David Mazurek who is awesome! He ensured I was comfortable with my new payment and thoroughly explained all elements of the contract I had signed. He is very knowledgeable and gave extra effort and ensured I received answers to my questions. It was a great experience where I did not feel rushed or pressured in any way! Acme Nissan makes you feel like family. I even received 3 years of basic maintenance for free! Looking forward to continued future business as well as servicing my car with Tom, Service Manager, and Team!

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.

Have bought a lot of vehicles there over the years always great experience there always helpful Just got an 08 f350 and could not be happier

I recently had the pleasure of trading in and purchasing my 2nd vehicle in 3 years from George Gregory at Sawyer Lyons GMC. Every time I visit this dealership (for service or sales), I feel welcomed and valued. George, who has always been both friendly and professional, always takes the time to say hello and that leaves a lasting impression on customers During the sales process, he has never pressured me into making a decision but instead encouraged me to take my time and ask questions. What really stood out, though, was his commitment to ensuring I got the best deal possible. He worked with the finance team to offer competitive pricing and tailored options that fit my budget. Throughout the negotiation, he was transparent, honest, and made sure I was comfortable with every step. Because of my experience with George, I feel confident in my purchase, not just because of the great car I was driving off with, but because of the exceptional service I received. It's rare to find a car salesman who genuinely prioritizes customer satisfaction over making a sale, but this one certainly did. If you're in the market for a new vehicle, I highly recommend working with him—his professionalism and customer-first attitude made all the difference.

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.

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.

Team was professional from the first contact. They did a great job in follow up. After the purchase they continue to follow up.

I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Dennis was professional from start to finish . All items that was taken care of and showed exceptional knowledge and care during m visit an our has of my car . Ask for Dennis when visiting the dealership

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
