New and used 2026 GMC Canyon trucks for sale near Mendham, 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.

I was finishing a purchase of a new AT4 b 2500HD I know that I can be a bit difficult, but Phil the Sales Rep and Amanda were just awesome to work with and handled every concern I had. Thank you both

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

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!

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!!

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.

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!

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.

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.

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

Tom did a great job servicing our vehicle and taking care of us quickly even though we did not have a scheduled appointment. Much appreciated!

We have worked through Frampton Walker for at least 5 GMC vehicles. He is our first call every time we need a new car or have an issue that needs to be addressed because of his professionalism, attention to detail, and he solves our problem.

My experience at Greenbrook Chevrolet was absolutely amazing. They made the car buying experience so simple and were very clear the whole time. I would highly recommend those looking for a new Chevrolet to come in and ask for Yannie!
