Amazing customer service! We have been to many dealerships and have leased multiple cars. This dealership has gone above and beyond, their customer service is impeccable! From We have been to many dealerships and have leased multiple cars. This dealership has gone above and beyond, their customer service is impeccable! From our very sweet salesman, Matthew, to the manager and business manager, Joe. Everyone was amazing. Very straight to the point, extremely pleasant staff. We got exactly what we wanted and could not have been happier. From start to finish, the entire process could have been anymore painless and smooth. We will be forever customers of Sun Buick GMC. I don’t know what you guys do with your staff, but whatever it is, keep doing it because you keep customers like us extremely happy! We will definitely be back to see Matt for our next car, what a pleasant man to deal with. More

The best in class! Had a long day of car shopping and made my way to Sun Buick GMC. I had my eye on a Terrain, but unsure if it fit all my needs. My salesman Darnell spe Had a long day of car shopping and made my way to Sun Buick GMC. I had my eye on a Terrain, but unsure if it fit all my needs. My salesman Darnell spent a ton of time walking me through the features and answering all my questions. Sun was by far the most professional, friendly and laid back delearship I have been too. I highly recommend Darnell if you are looking for a stress free car purchase! More
Great experience! Tony and Kevin were a pleasure to deal with. There was no pressure at all from anyone in the dealership and Tony was extremely patient and helpful. It Tony and Kevin were a pleasure to deal with. There was no pressure at all from anyone in the dealership and Tony was extremely patient and helpful. It took a couple of weeks for us to decide which car we wanted and Tony was very helpful each time we visited - answered question after question, lease, buy, test drive, the whole nine. Kevin was fair throughout the process and that ultimately finalized our purchase. The entire experience was great! The delivery process was as quick and smooth as any new car delivery I've ever experienced. Tony had us all signed up and ready to go! I'm looking forward to returning when our next car is ready.

My best car dealership interaction I have to start this with the fact that I hate shopping for cars and going to car dealerships. I find the whole process opaque and time consuming. I w I have to start this with the fact that I hate shopping for cars and going to car dealerships. I find the whole process opaque and time consuming. I work in Manhatan, and the last thing I want to do is spend hours in a dealership negotiating a car lease. After speaking with almost everyother dealership on Long Island I remembered that I’d trade emails with Mitch last summer. What a mistake I’d made not calling him back first. Mitch was a complete please to deal with. He was extremely patient with me not be able to make it to the dealership, given my schedule and we were able to coordinate the entire deal by phone. The best part about dealing with Mitch is my wife and I felt very comfortable with him, and also believe that he was very honest and transparent with us. Sun Buick was also extreme competitive with their pricing in comparison to EVERYother GMC dealership on Long Island. I will 100% deal with this dealership again, and also recommend friends/family go to see Mitch. More
Mike,Kevin and Joe are the best I went to a number of different dealers on the island but finally decided on Sun Buick GMC and it was primarily due to the honest, courteous and extre I went to a number of different dealers on the island but finally decided on Sun Buick GMC and it was primarily due to the honest, courteous and extremely knowledgeable Mike Kunz. There was no pressuring by anyone at Sun and Mike helped us out every step of the way. He went over and above what is expected in every instance. Joe and Kevin was receptive and extremely helpful all the way through the experience. Deffinitly will recommend Sun especially Mike, Kevin and Joe to everyone I know. Thanks to Mike for everything.

Mitch is the MAN !!! Mitch is very knowledgeable and works with you start to finish to get the deal done. He is one of the reasons I came back to get my 3rd car from Sun.

My 6th lease at this dealership I love my new car! I've been leasing for many years with SUN Buick GMC. We all live busy lives and via email is my best way to get things done. I pers I love my new car! I've been leasing for many years with SUN Buick GMC. We all live busy lives and via email is my best way to get things done. I personally knew I didn't have to test drive my new GMC Terrain, because I've been driving one the past 3 years. I picked out the color I wanted, the options I wanted and the day I wanted to pick my new car up. I have to thank Andrew Nagor. He is amazing, professional and personable! Thanks for making it so easy, Andrew!!! I also want to thank Joe and the owners. See you in 2021! :) P.S. I've received so many compliments on this model! Love the new look of the Terrain. More
The owner who won't take ownership Patrick Cassino is among the worst owners/managers that I have ever encountered as a consumer. I contacted him after a second wasteful visit to his s Patrick Cassino is among the worst owners/managers that I have ever encountered as a consumer. I contacted him after a second wasteful visit to his service shop for a recall repair in July of 2018. My car was at his shop for two full business days, and when I picked it up, it was in the same condition that I dropped it off in. According to the service consultant, the part that they arranged to have overnighted did not come in. When I came back more than a week later to finally have the work completed, the part was still not there. When I spoke with Patrick on the phone, he made every attempt to divert the focus of conversation away from my complaint. I found it exhausting trying to convince this man that the service and courtesy at his shop was less than perfect. At the end of it all, the only remedy he offered included me taking my car to another dealer, even though I bought it from Sun. I did, by the way. A GM dealership less than 8 miles from Sun had the part in stock and completed the repair in about 2 hours. When retail/business transactions go awry, consumers expect that there is a supervisor they could defer to who will listen with an open mind and offer an amicable solution. That is not Patrick Cassino. In his mind his shop is never wrong, his team is never at fault, and any problem that you have at or with Sun Buick GMC is just that - your problem. You don't have to take my word for it though. If you read how he replies to any online review that is unfavorable, you'll find a pattern of narcissistic responses that deflect responsibility from his dealership and his team. He is the owner who won't take ownership. More

Good experience This is our third vehicle at Sun gmc. One purchased and two leased. Our experience there was very well. After a service we inquired about returning ou This is our third vehicle at Sun gmc. One purchased and two leased. Our experience there was very well. After a service we inquired about returning our lease early. 36 mos out of 39. The first salesperson did not contact me back. 2 weeks later we returned and asked a different sales person. He was excellent. Very quick and promtly returned all our calls. We returned our 2015 buick encore and leased a 2018 gmc terrain. Andrew Nagor was outstanding. He made sure we selected our choice of trim and color. Very patient and answered all our questions. Great experience, and recommend friends to Sun gmc and Andrew Nagor. More
