I've never seen one of these before. The catalogue '1988' Fire Mountain (which apparently came out in 198

was black. This is the colour of the '1990' Fire Mountain (which apparently came out in 1989), but the specification is much more that of the '88', including the curved forks (but not, as has been said, the rear brake). So could there have been an interim range, between the '88' and the '90'?
As to price, how can that be expensive for a bike of some historical interest and in such fine condition, one might ask? It's interesting though that most people on this site seem to buy bikes to ride them, and it would be almost a shame to ride this, after it has been kept in such a good state for such a long time (especially if you're as clumsy as me). Whereas many of those who do battle on mtbr-vcr seem to be collectors of what are called 'garage queens', so you would think that they might be more interested in this kind of specimen. Except that it's a Kona, and they're more interested in Fujiwadas or whatever, which are extremely rare because only five were ever made (and it might be uncharitable to wonder why). So maybe you're right, maybe it is expensive. Blow it on a bad night out instead.
