Donna Coffman is the best! We have bought 5 vehicles from her over the last 20 years or so. She’s always informed about the vehicle we’re interested in, very helpful and down to earth. Donna never tries to pressure us into something we don’t want. She is the reason we keep coming back to Tillery.

My experience with the Service Department Team was super great today. Rudy, Service Manager, April, Service Assistant/Receptionist and Richard, Mechanic, worked seamlessly to get my car fixed in a timely and professional manner. I’m especially grateful to April for her special care and thoughtfulness for us. I don’t want to forget the Parts Department who was able to secure the part I needed before the expected time. I’ve purchased one vehicle here and would highly recommend this business to anyone who likes being treated special!

A++ Service from David and the entire team at Tillery!!! I had my eye on a brand new truck which was to be delivered to the dealership in 3 months. To my surprise, the truck came in within weeks and David called me the second it arrived. Happy to say, I am now the new owner of a great truck. Entire process was seamless.

DealerRater May 10, 2025

This is the forth vehicle we have bought from Tillery. No complaints. We feel we have always received great service.
