Klein Quantum, 2001-2002. Has Shimano 105 components (all). Owner says he rode it twice.

It feels really nice, the fit seems to be great for me, but the fellow wants $900 for it. I know these bikes used to start at 1700$ but given the age and all, what would you be willing to pay for this bike? Is he about right or can I talk him down, y'think?

EDIT: and my apologies for the thread title. I ended a sentence with a preposition... what on EARTH would my professors have said 10 years ago????
