Probably the best experience with a mechanic that I've ever had. He was very knowledgeable about the issue at hand. Did a excellent job and did it in a timely fashion. Also, he arrived earlier then he was scheduled which was a plus for me. Finally someone who knows his stuff.

I would, without hesitation recommend him to anyone I know and would gladly use him again.
