Used GMC Sierra 1500 trucks for sale near Millstone, NJ

Alexis did an outstanding job on the sale of my car. Very pleased with the purchase and dealership.

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!

We are really enjoying our new car! The staff was friendly and relaxed. We would definitely recommend them to friends and family. Looking forward to the right time to return for our next vehicle.

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 had a fantastic experience with Bladimir and team they went over the car top to bottom with me helped me out by suggesting the warranty 5 stars

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 !

Visited bc of great reviews and had a Kia I wanted to see. Didn't end up buying but not b/c dealership. All staff interaction was great, not pushy at all and clean space. If I see something again there I will still drive the 2 plus hours from Long Island

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 can honestly say that our experience could not have been any better. This is the 3rd car that we have gone through Mike Moursy,and he is excellent at his job.He is knowledgeable, personable , informative, and honest. We don't see any reason why we will not continue to use Mike and Freehold Subaru in the future. Our experience with the finance manager David was also great.

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 purchased a used vehicle on May 10 of 2025. I actually started the purchase on May 1, but it was for my business and took a little bit longer to secure funding, etc. I work with Frank, who was amazing. He was patient, kept me informed, helped me along in the process, and delivered the vehicle so smoothly. Zach, the finance gentleman, was also amazing. The entire process was smooth and easy, and I would absolutely go back.

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?

The process was easy and efficient. Everything worked out great and we got the car!

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

Matthew Lloyd was great . Excellent salesman and a great guy . I highly recommend his services

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 owners great people working couldn't ask for a better experience. Would recommend to anyone to buy a truck or car from Coleman and has a clean nice service waiting area

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

From start to finish they helped me with every speed bump they delivered on time the people I met were above and beyond from the dealership to the online sales having it delivered was fast and fun experience I love my new SUV they also shipped 5 hours away to me perfect 🤩 job team Car Shop 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!

Khader was very helpful. I came in looking for a car with a huge balance from my previous car and he helped me get into a newer car and helped me achieve the payment I was looking for. They are all very helpful and they are not the typical pushy salesman. A very nice establishment to purchase a car from. Thanks again Khader!

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.

From initial contact to after the sale, Johnson Ford was a pleasure to work with. No hassle, friendly, courteous, respectful and knowledgeable.

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 took a Mazda 6. The car looked better than in the photo. I arrived, looked at it, drove it and realized that it was mine.

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.

Dillon, Knows the thr cars good points and not good points. Willing to discuss them and how it will effect your comfort and driveabilaty. Also was willing to change the deal as circumstances dictated. The entire staff are friendly while professional and very straightforward.

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!

Great experience financing my first vehicle with this dealership and my sales rep Dylan Benton. He and the rest of the staff were very helpful and accommodating. They saw to it that I was being treated fairly and helped me get to the best deal I could get to.

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

Jeff, Mark, Jack, and all of the salesmen were extremely helpful and made the car buying process extremely easy. Thanks for being the best!

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...

Every time I get a service done the customer service experience is impeccable. Although I travel 45 mins out it is worth it because I do not get the same experience with GMC service companies closer to home. Keep up the great work and the staff is always warm and friendly.

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 have had the blessing of dealing with James Kovack two times - once in connection with the sale of my leased 2021 RAV 4, the other time witnessing the sale of my sister's 2021 RAV 4. At that time ( my sister's visit) based on my experience, she requested James to work with her. My sister's experience and mine mirrored each others. James was kind, patient, respectful, efficient, knowledgeable, and possessed all of the attributes one would expect in dealing with someone in his position. My sister's experience required a little more work and James, in consultation with his supervisor, Qu'ran Gordon, got the job done. Both men were as courteous and respectful of the situation as they could be and both men should be considered ASSETS to Carmax of Langhorne. My sister and I are most pleased with the outcomes of both of our experiences and will recommend Carmax, but in particular James Kovack and Qu'ran Gordon for their fine work.

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

Great experience from start to finish. Had everything ready for me when we arrived. Car was started and heated up for us to test drove.

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.

My experience at Greenbrook Chevrolet was absolutely amazing. They made the car buying experience so simple and were very clear the whole time. I would highly recommend those looking for a new Chevrolet to come in and ask for Yannie!

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.
