Realism

You know,every time I see Ed Brown and his slow,feeble body "build" I just cannot imagine this guy working on cars all by himself.Imagine him being bent over under a hood for an hour...he wouldnt be able to straighten out! You notice,you rarely ever saw any REAL repairs being made...just phoney screwdriver turns or reaching for wires or something "planted" under the hood.
Also,there was a rather rare Mustang that pulled in once.It was a "California Special" GT/CS.It was the one with the front fender primed over.(not the pilot episodes Mustang with the missing hubcap).
