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

When I shop for a car, it’s about function, not looks. This dealership was sharp, almost German-style. No fake grins, no emotional games. Just straight work. VIN? Ready. Service records? Ready. Paperwork? No surprises.

My vehicle was being serviced at service center.Staff was very polite.

Recently I wrote a complaint review regarding an issue I was having with Milea regarding collision body works repairs. The repair issues have been resolved. Milea Service Manager Angelo contacted me, service was performed on my vehicle, dents were repaired. Problem was corrected satisfactory. Milea made good.

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.

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

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!!!

I just purchased a Buick Encore from Buick GMC of Mahwah and I am thrilled all around. Gerald was patient, knowledgeable and so helpful. Jennifer, the business manager went out of her way to assist me through the buying process. The staff were all great and most importantly, I LOVE my new car!! Thanks for such a great experience.

The Rockville Centre GMC team did a tremendous job with my vehicle. They were timely and always was in communication with me about my vehicle

Tony was there!!! He was my go to guy for service on my three GMC trucks. He?s retired but still visits. Good to see him.

Andy is very knowledgeable and professional. He got my car in and out quick. It was fixed in no time. Love this Dealership. Mechanic is great also.

The employees at the Rockville Centre Dealership are always very accommodating. I have a very tight schedule and they always work with me to resolve any issues that I may have. The Sales and Service departments are A+. I highly recommend this dealership.

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.

great night tonight at Performance Buick GMC! Brian Gauthier was super-friendly, informative and made the process as painless and efficient as I have ever seen, and his tag-team partner in finance James Gavenas made the finishing touches of signing the final paperwork simple and fast, while clearly explaining all options and everything I was signing. and they gave me a great deal- Brian on the vehicle and James on the protection.

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.
