New and used 2026 GMC Sierra 1500 trucks for sale near Tappan, NY

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.

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.

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.

I recently purchased a used vehicle from Petar Ardeljan and it was a pleasure. This dealership operates differently from most as they encompass a no pressure environment and are transparent throughout the process. I would definitely recommend.

My old Buick was barely hanging on, so I came in for a new one. A guy from service even told me the best week to buy based on upcoming discounts. That’s not something you do if you only care about money.

I’ve had the Buick Enclave for seven months now and haven’t had a single issue. They even found the exact seat configuration I was looking for. Solid experience all around.

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!

My vehicle was being serviced at service center.Staff was very polite.

Bought a used Encore here a year ago and haven’t had a single problem. They gave it a full check and a clean history. No tricks, just a reliable car.

Great dealership to work with. I had the pleasure of dealing with Zeeshan, Willie and Akbar and I have to say it was the best interaction I had in any car sales. They were professional, courteous and actually cared about what we wanted. Most importantly, they were honest. Communication was too notch and I was updated every step of the way by text or call. They went out of their way to make sure we had the best sales experience from beginning to end. The car itself is beautiful and they didn't cut any corners in the sale. I wouldn't hesitate to recommend them to any one and when I'm in the market again will definitely be a return customer.

Thank you so much!! GMC of MahWah!! Knowledge and helpful service, If anyone looking for a car and great deal just go to them and you won’t be disappointed, Shoutout to my SALESMAN!! GERALD PASCUCCI.. He’s the BEST and he will explain everything you need to know and will make your dreams car happen!!

Great experience purchasing a new Buick Encore GX from a great team. Hugh Middleton was great to work with and he was patient as he explained the process and the numbers and he and his management were great at crafting a deal that was extremely reasonable and the process was smooth and efficient and I was in and out of the dealership in what for me was record time. Definitely the best car purchase experience I've had. If I need to purchase another vehicle I would definitely work with Hugh and his team again. I can't recommend them more highly!!!

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.

I just purchased a Buick Encore from Buick GMC of Mahwah and I am thrilled all around. Gerald was patient, knowledgeable and so helpful. Jennifer, the business manager went out of her way to assist me through the buying process. The staff were all great and most importantly, I LOVE my new car!! Thanks for such a great experience.

This dealer 100% is owed the most positive review ever! I never knew buying a car could be such an enjoyment! Start to finish best time ever! So happy! Thanks to Jaheim during initial phone shopping time, then meeting Moises sales and his manager Scott, who was so great and patient with me, to then getting to pleasure of meeting Jennifer finance manager who not only overcome credit obstacles she also made me feel like family after leaving her. Team you have there is unbelievable!

Wow best experience ever! Hugh sales, Jennifer finance manager, and Scott sales manager were all so unbelievable! Thank you thank you!!!

I don’t need “premium,” I need clear explanations. Rafael explained everything, even printed a simple chart about insurance. First time buying without my husband—and the first time with no stress.
