New and used 2026 GMC Sierra EV trucks for sale near Muttontown, NY

GMC in Rockville Center is one of the best car dealerships and car repair service places that I have been to in years. The people that work there are top-notch and the work they do is even better. Thanks, GMC Rockville center!

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.

This was a very good experience. North Bay has a straightforward and honest approach to their dealings with clear pricing and costs, good communication, and a friendly/helpful staff.

I bought a 2022 Escalade ESV in 10/2023. From start to finish there was no hassle I saw the vehicle and did not purchase for over 2 months shopping around for a better deal. I went to many Cadillac Dealers across Long Island and they did not take me seriously. When I told them what I wanted my payments to be they didn't even attempt to really search for a vehicle that could match my interests. This Dealership allowed me to test drive without prejudice and also were totally patient until I was finally able to clear title problems with my Credit Unions because of NY State Laws and then Finance with Cadillac. I was shown the vehicle features several times to at least get the vehicle off the lot. My payment was 1265.00.. but now I'm down to 1065.00 per month. I would recommend this Delearship to anyone in the world. They go above and beyond in Customer Service.

Friendly courteous dealership with interest in your personal satisfaction. Fair pricing and finance terms to suit your budget. Overall good purchase experience.

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.

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 deal. No gimmicks or nonsense. Thanks Sean for making it such a smooth transaction. When it?s time to for another purchase I will certainly be back.

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

Recently I wrote a complaint review regarding an issue I was having with Milea regarding collision body works repairs. The repair issues have been resolved. Milea Service Manager Angelo contacted me, service was performed on my vehicle, dents were repaired. Problem was corrected satisfactory. Milea made good.

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.

Excellent service. Ask for Delano Ashmeade. Smoothest and easiest transaction you'll ever experience. A1

As usual my experience with the sales department was excellent. This was our second vehicle leased with Wilbur.

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.

Great service Stanley did a great job in keeping us informed of the process and offered packages based on miles on car. Thank you. Great job

Jesus has been my go to guy for 15 years. Have bought 5 cars from this dealer very professional and knowledgeable. Dealer is in my town and close incase of services needed
