Great service and fast. Went in to have a engine light diagnosed and found out it was a warranty repair. The staff was great and got it in and out within 2 hours. Two weeks later, the car is running just as good as the day I got it.

This is the second car I have purchased from Bosak. I worked with Janelle on both deals and she was outstanding. Great service, great deal, and great experience. I recommend asking for Janelle if you are looking for a car.

Great experience with a great staff. Very friendly and loyal to their customers. Other dealerships pushed me aside when I was not able to come in or they didn't have what I was looking for, but Dan Edwards and the staff at Bosak kept in touch and were able to get me exactly what I was looking for at the price I needed.

My wife and I were traveling across the country towing camper. My truck had a fuel issue requiring tow to the dealership. The truck arrived around 4. The service department brought our truck right in and fixed the problem. The department closed at 6 my truck was finished 745. The management and staff made us feel like long term friends and making sure we were comfortable and updating us on progress.Quite frankly this was the best dealership service department I have ever seen 5 stars not enoughGreat job Anne Schmitt service manager and Ryan out mechanic!!! Thank you

After visits to a few dealers to look at used cars and not having the best out comes it was actually nice to have a dealer listen to what I was looking for and manage to work with me to work out a deal for a new car. The service people I worked with were extremely helpful and friendly.
