I go out of my way.....to drive one of my Porsches when meeting a client - especially for the first time.
It's my way of saying......this landscape and irrigation contractor prefers superior engineering.
EDIT - oops - misunderstood the question.
I typically don't hire anyone to do anything at my home - I do most of the stuff myself. But - no I wouldn't hide any of my Porsches - hell they are like works of art!
