This review has more to do with the ability to deal with the unexpected than it does a more routine repair. In this case the check engine light was on, traced to a air-fuel sensor gone bad. It sound like a simple repair, but the old sensor was frozen in the exhaust manifold due to heat and couldn't be removed. From there it got down to removing the sensor without doing damage to the manifold and further expenses. They where up front about the possibilities, not wanting to surprise me with further cost. In the end it was resolved with the professional know how of having experience with the unexpected before. I thought in the end it was a fair cost for an unfortunate situation.
