I'm not at all sure I agree with your thought process on that one.
It's similar to judging a potential buyer by their clothing or age.
And while I generally do the same thing unless otherwise advised, I do so as a courtesy. Many of the boats I've been on at shows, both in and out of water, have had carpet or other material down to protect any easily marred surfaces. The rest were pretty durable.
Just my buck thirty on it.
