Great dealership, Great sales person
We knew the car we were getting before we got there. Did check out on the internet before we went, made an appointment with Owen and went up. Was greeted by a nice lady who got Owen for us . He brought the car around and said to drive it around for awhile and he would checkout my trade. After all was said and done we got the car we wanted at the price we wanted and a little more for our trade then we thought.we met with the general manager and the finance man. Everybody there was fantastic!!! Definitely would recommend the dealership and ask for Owen he was great.

D’Ambrosio is a great place to buy a car.
D’Ambrosio is a great place to buy a car. I cannot say enough about Dave Baldwin. He has always taken the time to guide us to a great car. This is my second Mitsubishi from them. He was so understanding and patient with me. My daughters and I both appreciate the personal touch the dealership gives to you. Thank you again
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Fantastic experience -the buying and trade-in process was
Fantastic experience -the buying and trade-in process was very smooth and easy! Rob Ehrig found the perfect vehicle for me (GMC Terrain AWD), and I love it. He explained all the functions and features completely and helped set everything up (phone pairing, On-Star, etc.). I am very pleased with the experience and will highly recommend Star GMC as the dealership to use.

The first day I showed up no one assisted me or asked me
The first day I showed up no one assisted me or asked me any questions so I left. I then reached out asking if the vehicle was still available and was responded to very quickly. When I showed up to look Jeremy helped me right away and was very kind. Let me see all the seats because I am looking for a third row. Unfortunately that car was not right for me and he didn’t make me feel bad or like I wasted his time he was just happy to help me. I really appreciated that.

Just purchased a pre-owned car from them.
Just purchased a pre-owned car from them. Cameron Jensen made this the smoothest car buying transaction I have ever experienced. The car was priced right. They knocked a little more off. No junk fees. Everything was very straightforward. Would do it again if I was in the market.
