I said my max budget was $22k.
I said my max budget was $22k. In other places, they frown at that. Here, they calmly worked with me and found a great option without judgment.
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Great dealership to work with.
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.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Great purchase experience
John McCoy was a great salesman! He was honest, communicated well, and applied no pressure to make a decision. This dealership was the only one on Long Island that was willing to negotiate a deal on the car I purchased. Every other dealer said that they could not lower the price of the car even $1. This is the third vehicle that I purchased or leased from this dealership and I will return when I am ready for my next vehicle.

Great service, Great price, Great car!
We were very pleased with our experience at Honda of Tenafly. It had been 2 weeks that we were very actively looking for a pre-owned BMW X1. I saw the advertisement of Honda of Tenafly on Friday for a new entry they got matching exactly our requirements. The listing had no pictures as they had no chance to take some yet (nothing sketchy as someone could think). My first contact with them was via text and I have to admit that it was not a successful experience. I would not bother with that system and call directly the dealership. We spoke to Denise that answer all our questions and set-up an appointment for us. Arriving at the dealership we were treated by one of the salesperson, Lydia - very nice and professional. She located the car and brought it for us. The car was not even in the dealership lot yet as they just had finished inspection and were in the process of cleaning it. That stopped everything for us to see it. It was perfect! The car was a trade in with a perfect Carfax - one owner, low mileage, regular maintenance by a local BMW dealership - PERFECT! We decided to go for it! The dealer’s fees were minimum and it was a very transparent process. We didn’t have our checks on us so they allowed us to make a deposit via credit card ($5,000 max on cc per transaction), leave with the car and gave us a few days to bring back a check of the remaining amount. In overall, we are very happy with the process and we would highly recommend to deal with Lydia! She answered all of our questions and was very helpful.

Great Experience
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.
