New and used 2025 GMC Sierra 1500 trucks for sale near Parsippany-Troy Hills, NJ

Being a customer of Greenbrook GMC as a pleasant and rewarding experience. My sales team member Mike Santucci was awesome in every way and made the buying process smooth. All management was professional and supportive answering questions and making sure delivery was professionally done on time. I bought again at Greenbrook GMC because their service team and parts team are incredibly responsive and helpful with consistent exceptional service.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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.

Very good. I waited for repair and they made an effort to keep my wait as short as possible

Shelbey is the man you need to see! This whole process was a very pleasant experience.

Marilyn has awesome product knowledge found exactly what I was looking for. My experience was a smooth no pressure transaction.

Tito Palmela and TJ are awesome to work with. Tito worked to find me the perfect Yukon for my budget and needs. I LOVE IT!!!! These two are really there to help and both have checked in to make sure i was fully satisfied. Thanks so much guys! Highly recommend Green Brook GMC. Jennifer G.

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.

Tito was a very nice sales person. There was no pressure when we changed our minds on which truck to buy. We are very happy with the deal TJ and Tito gave us. We love the truck that we bought!!

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.

Thank you so much!! GMC of MahWah!! Knowledge and helpful service, If anyone looking for a car and great deal just go to them and you won’t be disappointed, Shoutout to my SALESMAN!! GERALD PASCUCCI.. He’s the BEST and he will explain everything you need to know and will make your dreams car happen!!

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.

I’m not techy, but I trust my gut — and this place felt real. Got the Envision, been loving it. Smooth ride, easy to park. They even called a week later just to check in. That small gesture made a big impression.

Great experience purchasing a new Buick Encore GX from a great team. Hugh Middleton was great to work with and he was patient as he explained the process and the numbers and he and his management were great at crafting a deal that was extremely reasonable and the process was smooth and efficient and I was in and out of the dealership in what for me was record time. Definitely the best car purchase experience I've had. If I need to purchase another vehicle I would definitely work with Hugh and his team again. I can't recommend them more highly!!!

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!

Johnson GMC is amazing from sales to service to finance! Jason and his sales and service team are fantastic, I would absolutely recommend this dealer, you will never go anywhere else!

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.
