New and used 2025 GMC Sierra 1500 trucks for sale near Plainview, NY

I was very pleased with the service received today. Stanley was very informative and helpful through the process. I used the Shuttle service one way and was extremely pleased.

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.

As a returning customer I already knew what to expect and the staff RVC GMC did not let me down. From my salesman, Mike Smith, the finance manager, Craig Novick and the general manager Ken Ryan were all a pleasure to sit and do business with and just ?shoot the breeze?! Nice bunch of guys and a great place to buy a vehicle!

if you go to this place ask for Oz... an absolute gentleman, and great salesrep ... very rare you find a man like that in the industry... overall 10/10 experience... never even asked me to write a review but my experience was too smooth not too

Stanley is a professional and great GMC RVC service department representative. He kept me fully informed about my vehicle?s service, and the estimated amount of time for the service.

I had a great experience at Generation Buick GMC with Joe Rossetti. He met all my needs, I will be recommending all of my friends.

It is no stress when I bring my car to RVC GMC. Each person I have dealt with has been helpful, friendly, knowledgeable, and professional. RVC GMC is reliable, efficient, and timely. The waiting room is clean and comfortable. There is a large TV and you can help yourself to a hot drink. I?ve also gotten a courtesy ride home from them.

Truck was as advertized very clean well taken care of spent a little to much time standing around at dealership I thought things went smoothly with purchase and we were of on our way home.

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.

Loved that the showroom has natural light—not cold fluorescent stuff. You can see every detail on the paint. Staff uniforms look sharp too—more like a boutique than a bank.

Great service from Zach. Very knowledgeable and thorough. Will definitely recommend him and Generation Buick GMC to my friends and family.

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.

Wow what a complete difference in professional service from Generation GMC in Sayville compared from King O'Rourke in Smithtown. Service department is amazing. They send you a video from the mechanic going over all the concerns that you have any what they found. I was constantly being told my oul leak was a seel. Thanks to Generation GMC they took the time to find the real cause and it's going to take a week to fix. Thank God had the issues at King O'Rourke otherwise I wouldn't have found an amazing dealership. Especially Thanks to Maria for keeping me updated.
