Used GMC cars for sale near Sussex, NJ

Stefanne Rivera was very professional and worked with me to get my car handed over AAA towing even though I was not able to get to dealer. She understood my condition and was very understanding. She and is a valuable asset to the company.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

great night tonight at Performance Buick GMC! Brian Gauthier was super-friendly, informative and made the process as painless and efficient as I have ever seen, and his tag-team partner in finance James Gavenas made the finishing touches of signing the final paperwork simple and fast, while clearly explaining all options and everything I was signing. and they gave me a great deal- Brian on the vehicle and James on the protection.

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

I was driving by this dealership and was happy to find it here on Cars.com too and now have a hub to their inventory on my favorite Car site! I am an online car shopping junkie of a sort and when I do decide to move on my next Used vehicle I will check Dover Used Car Center first because when I walked in I was treated as a person and not a target! Thanks for allowing me to browse and ask questions and not bombarding or pressuring me after. I look forward to doing business soon.

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.

from the beginning of inquiring about the purchase of a new GMC sierra 1500 to the completion of driving one home from John Jonson GMC. This was the best car buying experience I have ever had over the course of 30 years. Both the sales team and financial team were outstanding, friendly, understood what I wanted without also applying any sales or financial pressure during my vehicle purchase. I highly recommend this dealership to anyone looking for a GMC and will be returning when needing another new GMC vehicle in the future. DL

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

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

I have bought 2 vehilcles from this dealership and have had zero problems and will purchase another this year. Everything was seamless. I would trust this dealership and recommend them.

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

Love this dealership, just leased my 3rd car, special thanks to Jason, and Sales guys including Zach, Keith, Shelby, Josh, John Louie and Rich in Finance and the service department. They are professional, and really try to work with you to get you what you want and the best deal! I will never go anywhere else!!

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

My husband and I purchased a 2015 Mustang from Auto Valley! Oleg was our sales associate and he made the whole process very simple! We are from out of state but that did not slow down the process which is very impressive! Oleg was great at communicating with me every step of the way! Daniel was the manager that assisted us as well! Wonderful and EASY car buying process! Thank you ! Highly recommend!

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.

John and Clint at cars r us are great! They got me financed for the van that i wanted! The process was quick and easy! I found my van and in no time I was driving it! They were very helpful ! Any issue I may have had they were very willing to help ( i locally got a flat tire) and Clint came to my rescue! These guys really are great! Thank you again!

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

I wanted to thank Sussex Auto Group for all the help purchasing my daughters first car, very smooth and fast process there was no any hidden fees like the other dealers i visited prior visiting Sussex Auto Group. Definitely recommend them they also speak 4 different languages for those who arent fluent in English.

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!

Service was outstanding. Staff called with the cost before completing the work - very much appreciated. Thanks!

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.

Traveled 6hrs one way to get my dream car. Todd Porter is the man of the Year! Explained the car in detail over the phone and didn't disappoint. Thanks again.

Bluetooth/wifi issue....hardware replaced in a timely manner i hope it works....too much technology

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. :)

Many Thanks to Scott from parts and George from Service for their help and support in servicing my 2011 Pathfinder, i have been purchasing my Nissan's from this dealership since 2004, there pursuit for customer satisfaction is part of the culture ... Thank you

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.

George Gregory got us into the right car?.the process was painless. George was friendly and professional. This is our third car with SL and we?ll be back for our fourth.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

I purchased a vehicle, a GMC Terrain, from Performance yesterday, July 30th,from this dealership. Alex, Art and Brandon were all professional, courteous and extremely helpful. It was definitely one of my best buying a car experience I have had. Thank you all for the help and effort that was put into the purchase. I live in NY and it was still painless!

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.

Sean Dyer - very helpful worked with me understand my requirements. He stayed late after hours to make sure I closed on my lease that same day. Along with the office manager, who spent the time to explain my options and gave me the time to think through them before having to make a decision or commitment. Both made me feel a high level of trust that they had my best interest in mind and with that I went with the dealership and with both the manager and the sales representative because I trusted in the firm and them 100%. I now have a new dealership that I would be dealing with going forward and I’m very appreciative for everything they’ve done. I would recommend the dealership to any person interested in purchasing a new vehicle. This is my first Kia and I know I will be back again in the future.

I'm 6-4 so I'm looking for a comfortable vehicle that's easy to get in-and-out of plus is high quality. I don't buy new cars and in our 40 years of marriage it's the nicest used car we've purchased.

The buying experience at Performance was outstanding. Alex Kasper took care of us like family. His knowledge of the product is the best I've seen in any dealership, anywhere. He answered all of our questions and kept us informed about the status of our order at every turn. During the delivery, he took the time to demonstrate every feature of the vehicle, making us confident we could operate all of the amenities that came with the Yukon. Thanks also to Al, who made the financing and ownership paperwork process easy and efficient.

I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.

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.

Missing a few things that could really make it better. Homelink for garage door isn’t offered? Doesn’t come with a receiver type hitch however what does comes with it is almost the same amount of steel. The phone charger doesn’t work quite right and they know it.

We purchased our new Honda Passport . Our agent Kaia is amazing, she did the transaction smooth , quick and easy. Thank you Honda Sussex.

Bought a demo car . The Acadia has been great . Wife’s car . She likes it . Roomy and good gas mileage . Would also make a great road trip vehicle if I didn’t have a full size Ram .
