I bought a 2004 Trek 1000 about a month ago. It was only ridden once. Mint condition. The chain didn't even have dust on it.

I paid $400 and though I got a great deal. The bike shop got one like it a few weeks later and they sold it for $500.

I'd say if the bike is in really, really good condition like they say, it may be worth close to that.

A new one would cost you $1650. http://www2.trekbikes.com/bikes/bike...id=1444000&f=2
