The work I had done was difficult and complicated, ( a new timing belt, cam & crankshaft seals, on a 3.5L 24v interference engine), The owner was shorthanded that day and actually put in three hours overtime to finish the work on a Friday night. The estimate might as well have been chiseled in stone, Smittys charged not a dollar more than was quoted to me. I'm completely satisfied with the repair and highly recommend Smittys to anyone looking for a skillful mechanic where integrity is part of the service.
