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

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.

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.

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.

They helped me narrow things down to three great options based on my budget and trade-in. I ended up with a GMC Acadia, and two months later, I’m still sure it was the right call.

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

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.

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.

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

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.

They found me a Lexus UX with every feature I asked for—big screen, full trim. I had to wait a bit, but they didn’t outsource it from another state. Found it local. Worth the wait—this thing is a beast.

Seth was incredible to deal with and took all the hassle out of the process. I was able to get in and out in a timely manner and I?m thrilled with the truck I purchased.
