New and used 2025 GMC Terrain SUVs for sale near Hanover, 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.

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!!

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.

Didn’t feel like I was just buying a car — it felt like I was dealing with genuinely good people. Now driving a Buick Encore and still glad I chose them.

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.

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!!!

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.

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.

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.
