Great Expereience
This was the easiest car buying experience I have had. They took me to the car I was interested in. Keys were there, we drove it right away. The price was competitive, the financing was lightning quick. They washed it while I was signing and I was out of there in under an hour. They even drove me to turn in my rental car so I could just drive my new car home and surprise the family. First class business.

Great service. Except for
Peter was the first person who helped me and was very helpful, when I had a family emergency he held my Mustang till I could get in to see it. Kern was the individual who I saw when I was able to see the car. He was very helpful and got me quickly through the process. The only problem I had was the rocker stripe was missing on the passenger side is missing and they have not been able to get it replaced. Hopefully it will be resolved soon.

Made car buying both fun and easy
Had a terrific experience buying an XC-60. Ashley knew the car well and answered our questions directly. We asked to drive several cars before we chose the 2022 B5 but Ashley was patient and pleasant as we made the decision. Excellent dealership!

I had a great experience working with Jeff. He was super friendly, easy to talk to, and really knew his stuff. No pressure at all; just honest help and great vibes the whole way through. He made the process simple and stress-free, and I drove away feeling confident and happy with my choice. If you’re looking to buy a car and want someone who’s down-to-earth and professional, definitely ask for Jeff!!
