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

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!!

great communications. Sent the truck in via a tow truck and received notification that the vehicle arrived. From that moment forward I was kept current with communications up to and including that the vehicle was ready for pickup.

Surveys don't get to the real problems which I'm sure can be reviewed on the the daily footage. communication is key especially when you have so meany people that could.

Made a difference changing the trans fluid Thank you R. Smith

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.

George Gregory got us into the right car?.the process was painless. George was friendly and professional. This is our third car with SL and we?ll be back for our fourth.

Excellent service with my GMC Yukon Denali - very attentive and took me in without an appointment.

I recently purchased a used certified GMC Sierra from Sawyer Lyons.The sales and service experience has been outstanding.My salesman,Harold,and George with the paper work were great. Service and parts were also great. This is a fantastic dealership to do business. I highly recommend this dealership.

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

My first car from them was back in 2019. A Yukon XL. Then came the trade-in. Then another new one. Just picked up my third from them. A Buick Encore. And the best part? They remembered my name. That kind of consistency builds trust. People don’t rotate every six months here. Everything feels steady.

My first purchase here was kind of by accident. It was the closest dealership. But the second time, I came back on purpose. Because once you know they won’t lie or change numbers last minute, you stick with the place that gives you peace of mind. This place does exactly that.

I was in New Jersey for a week on business. Been meaning to upgrade my car. Stopped in. Raul got that I was short on time and handled everything fast. Gave me a test drive. Sent docs to my email. Finalized everything remotely. Three days later, I popped in, signed, and drove off in my new car. They even threw in a cargo mat.

I came back again, and just like before, no rush, no pressure. A normal conversation, test drive same day. Got myself a Buick Encore GX. It’s small but zippy. These guys really know how to make you want to return.

I’ve owned 9 cars so far, 5 of them used. Let me be honest, not every official dealer keeps the same standards when it comes to pre-owned. Got a 2022 Acadia here for a client - clean car, no repainting, original mileage, and the interior wasn’t “restitched,” like you often see.
