That comes from a professional mechanic. And I might add, a damn good one at that.
This is the reason why some people, especially first time buyers, won't even consider looking at an "Experimental." That is a fact.
I was in that camp myself and know plenty of others who felt the same way. It stems from fear. Fear of bad maintenance, poor build quality and in general, just getting burned. There is some history to each one of those scenarios.
That is why I have always had the opinion, and still do, that going "experimental," does have the drawback of reducing the market for the airplane, even if it is perfectly sound. Some people just won't bite.
That withstanding, if one is diligent, properly informed, does their homework and has some professional help, I see nothing wrong with the purchase of an experimental. There are some fine ones out there, for sure. In some cases, they are better built and more well equipped than production aircraft.
