It's refreshing to have a mechanic tell you that you DON'T need something done, and they WON'T charge you for the time it took to find that out.
These guys seem to be straight-forward, trustworthy mechanics, something you don't find often. You just need to have some patience, because they're usually scheduled out at least 3-5 days.
Pros: quality service, dependability
Cons: wait time, limited availability
