Reply to "Pantera #1447 - the search is over, the waiting begins"

There's no licensing required. Whether there SHOULD be is a good question often discussed. One shop owner who contacts home mechanics every day once told me he thought people should be required to demonstrate competency with tools before Sears (or even Harbor Freight) would be allowed to sell to them.... And I've often said there are people in the Pantera world I would not trust to correctly check tire pressures.
But practically, if someone is electricaly or mechanically incompetent and is in business doing this, poor or dangerous-quality workmanship will rapidly self-limit the scope of trouble they can cause. Not so unfortunately in the private sector. "Caveat Emptor" still applies to buying used cars.
