Sun GMC and Antony were very helpful every step of the way in the purchase of my new Sierra. Never pressured you into anything and were fully transparent, no extra sells, etc. At delivery, made sure I knew how all the features worked, definitely a great experience working with him. I highly recommend.

I went there for an air bag recall in the steering wheel and when I picked up the car the XM radio didn’t work. They had me drop the car off and they had it for most of the day. They called me and said that it was t their fault and if I wanted I could pay 450 for a diagnostic check. I told them my 2013 Buick with 77k miles Never had an issue ever, until I brought it to them. Everything worked fine until they touched my car. Manager came out, basically told me it’s not there problem and sent me packing. Considering I bought 2 cars from them I thought they would give me better service than that. Very disappointed.

Dealer response

We are disappointed that you would write something so inaccurate about the service on your 2014 Buick vin # 5GAKVCKD1EJ289078. A few verifiable facts: No one here ignored you. You spoke with our service manager and me, the owner of the dealership. I explained the obvious - a 13 year old vehicle can have a problem at any time. Your car also shows Two Accidents on CarFax and has not been serviced here in over 9 years. Replacing an airbag in the steering wheel has absolutely no effect on the XM radio reception. It's on a separate circuit. Please check the web. It is typically caused by an antenna problem or a module. You didn't even call us with an XM radio problem until two days After leaving here. You then brought us your vehicle a week later and we attempted to reboot the XM audio at NO Charge. So, no one 'sent you packing" or charged you $450 for anything. We also suggested that you get a 2nd opinion at another GM dealership. Why haven't you done that? Instead it seems that you'd rather place false blame on a dealership that offered to help you. It's an older vehicle; things can break. - Patrick R. Cassino, owner-president

Purchased a 2023 GMC Canyon Denali from Matt Fierst at Sun GMC in Wantagh. It was a very smooth and seamless experience. No Hidden Fees and No Hidden Charges. Would highly recommend him to anyone looking to purchase a GMC in the Long Island Area!.

Had an easy time shopping for my new Canyon Denali at Sun GMC. It was a painless process. Anthony made it quick and was very patient with me. He answered all my questions and helped me find the exact truck I wanted. He helped me set up OnStar and Sirius XM, plus he set up everything inside the truck the exact way I liked it and explained all the technology to me. He was great with my son and my mom while they were dragging along in the car shopping process.
