OK, decent value for money (if it's the right size for you), a bit "beige" ie there are better suspension systems out there, but it shouldn't be offensive to ride - just a bit bland.
What kit does it have? Ie which forks, groupset, stc?
Have you considered the fully rigid route? Some excellent Treks, specialized and Marins around from the mid-90s. 24 speed, V-bralkes, no bouncers to go wrong. Just get out the saddle and flex your arms on the rough bits. Pure simple fun
Ive been thinking about the giant xtc as well, from my research and playing with them they are noticeably heavier than other brand bikes in the same price range but giant brand hydraulics are actually really very good. I think the 2008 cannondales are worth a look too, they all come with lovely flush welded frames and good forks.
If you are looking to flog the old wheels let me know, I building up an old marin single speed but only have an odd set of wheels, (and no handlebars and stem )
