Used GMC cars for sale near South Brunswick, NJ

Such a pleasant and welcoming reps! I appreciated that they were thorough & knowledgeable when it came to the cars they showed me. I also appreciated the transparency when it came to financing and helping to find the best vehicle within my budget.

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

Chris was very helpful. I ended up driving 3 hours to buy the car from him instead of my local dealer. Great customer service

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.

Stream lined efficient process with courteous staff. I had a phone call telling them what i was looking for and they delivered without much back and forth. finance process was easy. will definitely be going back. randy was awesome.

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

We had a very positive experience dealing with Matt and Marty. Both were very pleasant to deal with. We would definitely recommend them to our family and friends.

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 !

Overall, I had a good experience here. My sales rep, Miguel, was fantastic. He was very personable and accommodating. I came in with a specific car in mind that I found online. I was able to test drive it right away and bought the car that same day. My trade-in process was pretty seamless as well. I felt I got a fair price and they handled everything. I felt like they were a little unwilling to work with me on the price of the car that I was buying as well as some of the add-ons and other fees. But what can you do? My one complaint would be about the manager that was working that day. I could overhear them discussing my situation with the trade-in and my requests for negotiation, and it was quite disrespectful not just to me, but to the sales rep as well. If I was working directly with that individual, I would not have bought the car. I am not lowering my review because as I said, I thought my rep was fantastic, but I will remember that the next time I want to buy a car.

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. :)

I had an excellent experience at Bristol Auto Mall. The staff was knowledgeable and helpful, and they made sure I found the perfect car for my needs. They were patient and understanding as I worked through the financing process, and I left feeling confident in my purchase. I would highly recommend this dealership to anyone in need of a new or used car.

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!

No pressure approach, honest opinions and suggestions from the sales representative. Car was promised and delivered on time. No issues with this transaction and I would visit this dealership and salesman again.

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.

Very informative when requesting information via email as requested. Honest and straightforward answers to my questions.

If buying a car always went like this, people wouldn’t dread it. The team was on top of everything and the process was effortless. Cara Z was fantastic—no salesy nonsense, just honest knowledge and great energy. Picked up a 2025 Honda Ridgeline that looked exactly as advertised. 10/10 would shop here again. Erika was great too!!!

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.

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

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

At other dealerships, salespeople stick to you like flies to honey. Here - silence. And that’s incredibly appealing. If I hadn’t seen it myself, I wouldn’t believe it.

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.

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.

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!

Bill Heron was great! The entire staff from start to finish a pleasure to work with.

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.

We had a great experience today with Dylan. He was very helpful and logical and friendly . Thank you for all the great work Dylan! Max and Eric

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

Great service no Complaints Looking Forward to Purchasing a Vehicle. Waiting to Get my payment

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.

What can I say. Overall a great experience. They really enjoy what they do over here and the stock of cars is amazing!! One word of advice is make sure you check every small detail. The sales people can miss details and so can you. They move cars QUICK here and the sales reps on a Saturday seemed very busy!! The dealer had burgers and drinks to share with us while we waited which was awesome. Before I met the owner and his son, I was getting the feeling this was a family business, and it is! Really a great experience and awesome selection of cars. A++ dealer for used high end cars!

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.

This is my second time purchasing a car from JS Autohaus 6 and I'm sure there will be a third time in the future(1.5 Hr drive from my house may I add). They are friendly, professional,helpful,and do not force anything on you. Eli and Khader are great people. Would recommend to anybody.

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.

Excellent experience, love my new car! Friendly easy going staff, not pushy! The anti “used car dealership” dealership.

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

I had an absolutely outstanding experience at Road Ready! From the moment I walked in, I was greeted warmly and made to feel like a valued customer. The entire team was professional, knowledgeable, and went above and beyond to ensure the process was smooth and stress-free. My sales representative, Mina, took the time to really listen to my needs and helped me find the perfect car without ever feeling pressured. They explained all my options clearly, answered every question with patience, and provided honest guidance throughout the process. The finance department was equally impressive—transparent, efficient, and committed to helping me secure the best possible deal. What could have been a long and complicated process was made simple and seamless. The dealership itself was clean, modern, and welcoming, with a great selection of vehicles to choose from. I truly felt supported from start to finish, and I drove off the lot with complete confidence in both my purchase and the dealership’s commitment to customer care. If you’re looking for exceptional service, fair pricing, and a team that genuinely cares, I highly recommend Road Ready Auto Mall. This was hands down the best car buying experience I’ve ever had!

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

A very pleasant place to buy a car. The salon has a calm atmosphere, and the managers behave professionally and politely. The deal was drawn up without any problems, everything went quickly and clearly. I especially liked that no one imposes anything, but on the contrary, they help you find a car that really suits you.

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.
