New and used 2025 GMC HUMMER EV SUV for sale near Piscataway, NJ

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.

Not good at first, I had to take my vehicle back twice

The whole team at freehold Buick gmc went above and beyond to make me a satisfied customer. They took care of my problem in a professional manner. Actually called me a few days later to make sure I was good! I’ll definitely be back!

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.

Shelbey is the man you need to see! This whole process was a very pleasant experience.

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.

We have bought or leased 4 cars from Coleman. The sales staff is friendly and capable and the service service department is very professional.

I have been with this dealership for 30 years and I have recommended this dealership to family and friends because CUSTOMER SATISFACTION is important to them. From the sales people to the service department, they are professional, courteous and everyone tries hard to make sure your experience buying a new or used car is a great one. I bought my grandson's 1st car at this dealership and he now understands why I but my cars with this dealership.

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!!

Johnson GMC is amazing from sales to service to finance! Jason and his sales and service team are fantastic, I would absolutely recommend this dealer, you will never go anywhere else!

Always have had good experiences in service. Always smooth and honest. Have had nightmare experiences else where glad I found somewhere I can trust bringing my car to.

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

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.

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.

Our salesman, Will Oese, spent the day finding us the perfect vehicle. We spoke to him months before our lease was due, he was very knowledgeable and sent us different options. When we scheduled the appointment, we were only coming in to look at cars, but we had such an awesome experience with Will, that we left with a new car same day. We highly recommend Will Oese, Jesse Embry, Chris Tandy, and Claudia for all their assistance that day!

I recently had the pleasure of trading in and purchasing my 2nd vehicle in 3 years from George Gregory at Sawyer Lyons GMC. Every time I visit this dealership (for service or sales), I feel welcomed and valued. George, who has always been both friendly and professional, always takes the time to say hello and that leaves a lasting impression on customers During the sales process, he has never pressured me into making a decision but instead encouraged me to take my time and ask questions. What really stood out, though, was his commitment to ensuring I got the best deal possible. He worked with the finance team to offer competitive pricing and tailored options that fit my budget. Throughout the negotiation, he was transparent, honest, and made sure I was comfortable with every step. Because of my experience with George, I feel confident in my purchase, not just because of the great car I was driving off with, but because of the exceptional service I received. It's rare to find a car salesman who genuinely prioritizes customer satisfaction over making a sale, but this one certainly did. If you're in the market for a new vehicle, I highly recommend working with him—his professionalism and customer-first attitude made all the difference.

Gary was fantastic! I told him exactly what I was looking for, he helped me find the perfect car based on my needs and budget. Process was quick and he even took the time out to connect my phone and show me all of the features the car had!
