New and used 2026 GMC Sierra 1500 trucks for sale near Upper Montclair, NJ

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.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

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.

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Jonathan Cadme made my car buying experience easy. He was nice and transparent. I will recommend him to friends and family.

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

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.

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!

Excellent service. Ask for Delano Ashmeade. Smoothest and easiest transaction you'll ever experience. A1

They were professionals, Jonathan Cadme went above and beyond with helping with my car. I recommend him.

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

It’s nice that besides Buick and GMC they also have many other brands on the used lot. I came for a Canyon but noticed a clean Lexus. The manager showed me both without pushing me in one direction.

I was surprised by the service that Bomnin provided. Jonathan Cadme by far did an awesome job.

The funny part is they’re really close to the city. You can jump out of Manhattan, drive down Kennedy Boulevard, and you’re already on the lot. Once I got stuck in traffic and just messaged through the website form, they moved my test drive without drama.

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.

Rob was great I love my truck. We go way back. It was a simple process.

Service has been good too. I work nearby and bring my car here for maintenance. I call to schedule, and when you arrive they already know what needs to be done.
