It does look factory fresh - I had an SE that turned up that was like that, I mean the cables were supple, and it even smelled new too! I would love to know how these examples were stored, to end up like this. It might help all of us to preserve the compact macs that we already have, a bit longer.
As for price, I think the market for Classics right now is still going up as more of these succumb to cap issues (from the few of these that I have worked on, these little buggers go bad fast when they go - the compact electronics allows the cap goo to do more damage) and it also depends on what the collector is looking for and what additional items come with it e.g. the original box, original packaging, disks, power cord, mouse, correct keyboard and whether any yellowing is present. Also, your venue is going to dictate the price
The realistic range for these models is probably from 30 to 180 dollars in the US, obviously having more of the original 'stuff' is going to help the price, but re-capping for this model is needed to ensure that it still works when you want to sell it. I think that you would need a 'hook' of some kind to get much more than that - something really unusual, which would make it stand out from the rest of those on the market.
