They answer my questions on car theory every time I'm in their shop. I came in and they had questions for me to anticipate what the problems were. With the opportunity to charge me for a 16 spark plugs and labor because I went in thinking this needed to be done, they advised me otherwise that I had several thousand miles left on them and not to change them out. I appreciate that. At this point I come back because of the piece of mind I get knowing they'll be honest with me.
