If you are in the market for another vehicle, please go Steve Ahern! He will take care of you. Amazing customer service. The best! He went out of his way to get me what I wanted. Even though I did decide to go a different route, I couldn’t have had any better customer service than what he offered.

The team at Star is absolutely amazing!
The team at Star is absolutely amazing! My family has bought multiple cars from them and every time we are treated with the upmost professionalism. The deals are always extremely fair especially with the lifetime warranty that is given.
A little expensive, but comfortable, quiet, smooth ride.
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Well done!
Regular service, oil change, grease and tire rotation. The car needed a good wash and they did that too. All very timely and at reasonable cost. We bought this car used and have been getting it serviced here since buying it. Service has always been wonderful.

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.
