The best way to tell if a shop is good - take a look around. If you see parts and tools laying all over the place, it's obvious the mechanic's are disorganized. How do you think they'll treat your motor? "Cleanliness is next to Godliness" my parents used to say. I may be messy when with WCS's tools, but I put them back after the job is done!

Moral of the story: what you see is what you get.
