New and used 2026 GMC Sierra 1500 trucks for sale near Hackensack, 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.

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Austin Rizzotti was very professional and made the purchase of our new auto a real pleasure. He never pressured us to make a sale. The experience was different from any other car buying we have had.

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

Everyone was nice and communicated well. It was easy to work in the service lounge and I enjoyed the coffee there. I would schedule more service here in the future.

I worked with Arnold Polanco and he was great. From texting and talking he was able to find just what I wanted and made the whole process very easy. He even put a big bow on the front so my wife could take a picture or her new car with it. I would definitely recommend working with him.

Rob Birchall and the team were great. Was towed in on a Saturday and they were able to diagnose the problem and have me back on the road in 90 minutes.

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

I bought my 2025 Sierra EV out of state but am here in Long Island for a few months working and Rockville Center GMC was the only GMC dealership near by who would honor my GMC warranty. They have been great!!

I?ve been bringing my truck to the Rockville Centre GMC service department three or four times since purchasing it in 2021, and every visit has been a great experience. The entire service staff is amazing?professional, friendly, and genuinely helpful. The service manager is always around, easy to reach, and makes sure everything runs smoothly. I?m very glad I bought my truck from these guys. It?s a great local dealership, and I highly recommend their service department.

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.

Excellent service. Ask for Delano Ashmeade. Smoothest and easiest transaction you'll ever experience. A1

Jonathan did an excellent job at showing me the car. He made me feel comfortable and no pressure at all.

My vehicle was being serviced at service center.Staff was very polite.

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.

great communications. Sent the truck in via a tow truck and received notification that the vehicle arrived. From that moment forward I was kept current with communications up to and including that the vehicle was ready for pickup.

Surveys don't get to the real problems which I'm sure can be reviewed on the the daily footage. communication is key especially when you have so meany people that could.

Nice work, clean facility, courtesy and amaability, overall good job !!!bla, bla, bla, bla, bla, more and more and more bla bla bla bla blaaaaa

We have worked through Frampton Walker for at least 5 GMC vehicles. He is our first call every time we need a new car or have an issue that needs to be addressed because of his professionalism, attention to detail, and he solves our problem.

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!
