Wow. That is in amazing shape. To the average joe it's probably just an old Honda in really good shape, but to someone that know's what they're looking at that is quite a find, even if it's not really a rare model.
In my area, to the right person, that's a $3,000-3,500 bike. Thought their value will only go up from here.
But I'd say ride it and enjoy it. Sadly, it'll probably never be worth a small fortune, so enjoy a gorgeous bike while you can and let the next guy worry about miles.
I'd hate to see it parked outdoors. Once the sun starts hitting that thing, and rain starts creeping in to every nook and cranny, it'll start deteriorating quickly.
