New car buying made easy.
New car buying made easy. The entire deal was completed through email and over the phone. Jason Davis was friendly and helpful. He answered my questions in a timely manner and made the experience simple and hassle free. The vehicle price was straightforward with no haggling required. I felt like I received a very fair trade in on my truck.

Overall good drove over three hours to arrive, pain that
Overall good drove over three hours to arrive, pain that policy is they don?t accept checks or certified checks when purchasing outright. Did money transfer before leaving home and waited an hour at dealership for verification of transfer total four hours (ridicules). Other than that process was simple enough.

As usual, very good service.
As usual, very good service. Chad Boxdorfer was there as soon as I got out of the car. He was very polite and courteous. Got the car serviced and ready to go in the time he told me. Dave H.
