I recently bought a car from Sun Buick GMC, and it was honestly one of the best experiences I’ve had at a dealership. From the moment I walked in, everyone was welcoming and eager to help. My salespers honestly one of the best experiences I’ve had at a dealership. From the moment I walked in, everyone was welcoming and eager to help. My salesperson, Matthew Fierst, was fantastic. He really listened to what I was looking for and helped me find a car that was perfect for my needs and budget. I never felt rushed or pressured, which made the whole process a lot less stressful. One thing that really stood out was how upfront and transparent everything was. No hidden fees, no last-minute surprises. The finance team also worked hard to get me a great deal, which I really appreciated. When I picked up my car, it was spotless and ready to go. Matthew even took the time to show me all the features and made sure I was comfortable before I left the lot. Overall, my experience at Sun Buick GMC was outstanding. If you’re in the market for a new car, I highly recommend checking them out. They truly went above and beyond to make sure I was happy with my purchase. More

In my 69 years having dealt with many dealerships, I have to say the Sun group is absolutely the best to date. From the owner, Mr Cassino to the salesman Justin and financial man Victor I was treated with re to say the Sun group is absolutely the best to date. From the owner, Mr Cassino to the salesman Justin and financial man Victor I was treated with respect, courtesy and professionalism. One would think I was spending 100k rather than buying a used vehicle. Seeing I can only rate 5 stars I would easily double that. In the past shopping for a car was aggravating, but dealing with Mr Cassino and the Sun group was a pleasure. I have already spoken with family and friends regarding my experience. I confidently recommend Sun Buick Gmc to those with ears! Respectfully Jim Lawrence More

Justin took the time to learn about what was important to me while buying my first car and patiently went over options to help fit my budget as well as reviewing the difference between buying and leasing a car. This is the third vehicle that my family has leased/bought from this dealer and we highly recommend Justin and all the other salespeople we had the pleasure to interact with during the process. My Buick Encore has not only met my expectations, it has exceeded them. Thank you SUN for a pleasant experience! More
