My sales person at Castle Chevrolet was Tony Twall.
My sales person at Castle Chevrolet was Tony Twall. He was awesome to work with. He answered all my questions and was very knowledgeable. I have to say that this was the best vehicle buying experience I have ever had. My next purchase will be with the Castle dealership in McHenry IL and I will ask for Tony to be my sales person.

I just wanted to say Tim Hoffman in service exceeded my expectations. I bought a 2016 CT6 from a dealership in Crystal Lake. I put 300 miles on the car and noticed something was not right with Transmission good thing I had the extended warranty. Tim coordinated everything it was a big job and he coordinated everything with warranty company and kept me updated on status. Thanks Tim one of the best dealership experiences I have had with a dealer. Al B
