New and used 2025 GMC Sierra 1500 trucks for sale near Peapack and Gladstone, NJ

Best experience I've ever had with a dealership service department! Michelle and Jack picked up my car and returned it to me!! Friendly, clean, pleasant and competent. So rare these days. I would recommend them highly, especially over Freehold Buick. Freehold Buick tried to rip me off on several occasions. They lied to me and were disrespectful. I'll never go back to Freehold Buick, but look forward to working with Jim Curley Buick of Keyport in the future. Thanks so much.

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.

I bring my car back to this dealer for all of my servixe and repairs. They are always great about explaining things to me and getting things done quickly. I'm very happy with their service.

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.

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

Not good at first, I had to take my vehicle back twice

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.

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.

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

We have bought or leased 4 cars from Coleman. The sales staff is friendly and capable and the service service department is very professional.

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!

Our salesman, Will Oese, spent the day finding us the perfect vehicle. We spoke to him months before our lease was due, he was very knowledgeable and sent us different options. When we scheduled the appointment, we were only coming in to look at cars, but we had such an awesome experience with Will, that we left with a new car same day. We highly recommend Will Oese, Jesse Embry, Chris Tandy, and Claudia for all their assistance that day!
