New and used 2025 GMC Terrain for sale near Scotch Plains, NJ

The best dealership I’ve ever dealt with. The service department is outstanding. Appointments are easy to get and the repairs are always done quickly and completely

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.

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.

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.

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.

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!!

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.

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.

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