Short and sweet. I've had all kinds of work done on two heavily used cars, big and small... and Joe & co. always do fine work.
I've never scratched my head over the size of the bill (which is quite common with mechanics) and I've never had to wonder about the job because they guarantee their work. They're glad to talk about whatever the issue is, and basically you feel well taken care of.
I would assume that all of Joe's customers are like me: glad they have a really good neighborhood car guy.
