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

Came in just to browse. Then I sat in a Buick, took it for a spin, and boom — bought it. The vibe was relaxed, the staff wasn’t pushy, and the whole process was easy. No regrets at all.

Stopped in with a friend just to "have a look." Next thing I know, she picked a Buick Encore GX with a red interior I wouldn’t even choose in Sims. The dealership space is super cozy and photogenic. I was lying on a couch while she debated carpet colors.

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.

Was really anxious about the whole process, especially the paperwork. But the team walked me through it step by step and even helped with my insurance right there. Huge weight off my shoulders.

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.

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.

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.

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.

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.
