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

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 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

Clean, modern, relaxed. Even if you’re just browsing, nobody’s hovering or trying to close a deal. Great selection, and the manager handed me a few keys to explore on my own. Zero stress, just a good experience.

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!!

If you want to be treated like a person—not like a loan number—this is the place. They helped me trade in my car, gave me a fair price, and explained everything without the usual runaround. The car was exactly as described. You don’t find places like this often.

I double-checked Yukon prices online, expecting them to shift once I showed up—but nope. The number I saw on the site was the exact one on the final contract. Fees were minimal and fully transparent. It’s rare when things actually match up like that.

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!!!

Bought an Envision two weeks ago and already got a follow-up from the manager just to check in. It’s a small thing, but it says a lot about how they treat customers even after the sale.

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.
