Rence & his crew are the best! They really helped me out when I bought a used vehicle from a private seller who had apparenlty taken out a bulb so the engine light wouldn't come on. After I bought it, I was required to have the emissions tested. It.failed. I got the bulb replaced & found out it needed A LOT of work...about as much money as I bought the thing for! ***Let me get on my soapbox here & say that any county in WI that requires emissions testing should also have a law that a passed emissions test be given with the sale on any used vehicle. Off soapbox now.*** Rence replaced one catalytic converter, hoping the engine light would stay off. Bad news: the light went back on.That meant the 2nd catalytic converter had to be replaced for double the money. This was not a cheap thing to do, especially for someone like myself...a single mom living on a not even a 40 hour a week job. Rence really went above & beyond to help me and I know they gave me a huge deal when I had to come back to replace the 2nd catalytic converter. I highly recommend Rence for all your auto repair needs!
