I've been bringing my car to Campus Garage for years. On the most recent trip I noticed the "check engine" light while driving to campus but instead drove directly to Campus Garage. Despite that their lot was crammed full of cars (it was the Monday after the July 4 holiday), they didn't bat an eye. A couple of hours later Eric called to say the problem had been diagnosed, the parts ordered, and they could do the work after the parts arrived whenever convenient to me. The work is done and everything is fine - as is usually the case.
