If he wraps them all in anti-static plastic, bubble wrap, and boxes them up, he could put those away somewhere safe for 30 years and then sell them for a mint as a collection later on. In terms of investment, I think he might be on to something there. As for the guitars themselves though, SO not my taste. But as they say, one man's pleasure is another man's pain, so kudos to him for indulging his fantasies there. :)
