New and used 2025 GMC Terrain SUVs for sale near Boonton, NJ

They actually listen. No sales lines like “these won’t last” or “someone else is already interested.” Just respectful, pressure-free help. It made the process easy and comfortable.

I came in with just a few questions, and they welcomed me like a regular. The manager walked me through the Terrain’s features while I sipped on coffee—no pressure, no sales pitch. Honestly felt more like chatting with friends than being at a dealership.

You can feel right away that the staff genuinely care. I came in solo, with no experience buying a car, and they walked me through my options patiently, explained everything, and never once pressured me. That kind of honesty and calm isn’t easy to find.

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

Stopped by just to see the Encore GX, and ended up checking out a Terrain, a Sierra, and even a few Jeeps and BMWs. Being able to compare that many options side by side at one dealership? That’s a win. The fresh Sierra with the Pre-Certified package especially stood out.

Everything was dialed in from the start. I was greeted right away, shown exactly what I came to see, and given time to explore without hovering. The team clearly knows what they’re doing—paperwork was quick, smooth, and painless.

The experience and professionalism we received from Mark and the team at the Bomnin was amazing.

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.

It was quick recall service. Staff was hospitable. Provided good pick up rides from my work place. Dealership maintains a class of its own. A visit is worth.

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.

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.
