They treat people like they would want a family member of theirs to be treated.

We had a great experience at Pettyjohns, buying a car. The salesman and the tech help were great. Thanks so much! Robert and Barb McCully

Buying a new Chevrolet and trading my old vehicle was the easiest new buying experience that we had ever had. Everyone was very friendly and no pressure to add options on to the sale.

Friendly, professional staff made the car buying process simple and straightforward. They really went the extra mile. Would recommend James Slatten and his team to anyone looking for a new or used vehicle. Good hometown folks.

This is the best dealership I have ever dealt with. There was no back and forth dealing to try and jack the price up. Larry Crone was the politest salesperson I have ever dealt with. I would call him again if I was looking for another vehicle. Larry Vanzandt, Finance Director, was very polite. During the entire time I spent buying my wife a car, no one tried to pressure me. My wife and I drove 1 1/2 hours one way to the dealership. It was worth the drive. I am going to recommend Pettijohn Auto Center to my friends and family.
