New and used 2026 GMC Sierra 3500 trucks for sale near Summit, NJ

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.

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. :)

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.

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

I purchased a vehicle, a GMC Terrain, from Performance yesterday, July 30th,from this dealership. Alex, Art and Brandon were all professional, courteous and extremely helpful. It was definitely one of my best buying a car experience I have had. Thank you all for the help and effort that was put into the purchase. I live in NY and it was still painless!

The buying experience at Performance was outstanding. Alex Kasper took care of us like family. His knowledge of the product is the best I've seen in any dealership, anywhere. He answered all of our questions and kept us informed about the status of our order at every turn. During the delivery, he took the time to demonstrate every feature of the vehicle, making us confident we could operate all of the amenities that came with the Yukon. Thanks also to Al, who made the financing and ownership paperwork process easy and efficient.

Chris was the best to deal with; quick and to the point would definitely buy another vehicle from him. Young boy but knows his profession.

Love this dealership, just leased my 3rd car, special thanks to Jason, and Sales guys including Zach, Keith, Shelby, Josh, John Louie and Rich in Finance and the service department. They are professional, and really try to work with you to get you what you want and the best deal! I will never go anywhere else!!

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.

They often have service specials like discounts on oil changes or brakes. I was skeptical and thought it was bait. In reality, the bill matched the special on the website and they didn’t add anything extra.

The sale person Tom.help us out a lot great customer service! Was very knowledge able! Went beyond customer service excellent ! Felt like family! I recommend this dealership for the outstanding sale person Tom and all the people that work there very nice not pushy!

I am a new customer to the Johnson auto group, and after my experience will certainly be a returning customer. The sales staff, specifically Shelby, was amazing. They were attentive, fair, reasonable, and transparent throughout the entire process. I am so happy I decided to purchase from Johnson GMC. Ultimately, I left the dealership with a new truck and a great experience where I felt that I was a valued customer and that my business was truly appreciated.
