New and used 2026 GMC Sierra 1500 Denali trucks for sale near Summit, NJ

Rob Birchall and the team were great. Was towed in on a Saturday and they were able to diagnose the problem and have me back on the road in 90 minutes.

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.

We bought a car for my grandmother. I just watched. They spoke softly with her, never rushed, explained clearly, and didn’t talk down to her. That respect meant a lot.

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.

Bought a Sierra for business. Needed hauling capacity and durability. They helped me spec it right, and the price was fair—I checked around.

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.

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.

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!

Jeff Moran is a true sales consultant professional ! He listens to the buyer to find out their needs and wants. Being an advocate for the consumer is second nature for him. He treats people the way he would want to be treated. I highly recommend any vehicle buyer to reach out to Jeff......you will not be disappointed. :)

Nice work, clean facility, courtesy and amaability, overall good job !!!bla, bla, bla, bla, bla, more and more and more bla bla bla bla blaaaaa

from the beginning of inquiring about the purchase of a new GMC sierra 1500 to the completion of driving one home from John Jonson GMC. This was the best car buying experience I have ever had over the course of 30 years. Both the sales team and financial team were outstanding, friendly, understood what I wanted without also applying any sales or financial pressure during my vehicle purchase. I highly recommend this dealership to anyone looking for a GMC and will be returning when needing another new GMC vehicle in the future. DL

Bluetooth/wifi issue....hardware replaced in a timely manner i hope it works....too much technology

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.

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.
