John showed up on time and was extremely courteous and knowledgeable. The shop sent him out with the wrong part (not John's fault) but he was very quick to resolve the issue, he was back with the correct part from a local store very quickly and had everything completed in just over an hour! That's including the time it took him to go back out for the part! Was quick, nice, and honest. Will use Yourmechanic.com in the future and will request John again.
