    Our good friend Ron Ananian says, “Good mechanics aren’t expensive, they’re priceless!” Mr. Kilmer you are a shining example of how true it is. You’re a natural in front of the camera too. I would like to see you in all my favorite automotive programs.

    This video just answered my question. I have the engine light on for the catalytic converter AND it wont go past a certain speed. I know who's working some overtime to pay for this! Thanks Scotty! Much appreciated.
