It seems the final prices on ebay are all over the map on Litespeeds since there are not a lot being sold, much less in the same size. So what would a fair price be for a 2004 or 2005 Tuscany be?

grupo? wheels?

The Tuscany is a really nice all-round bicycle frame, and for "used" in the 2004/2005 vintage should fetch $750 to $1250 for the frame, fork, and headset bearings.

Ultegra level groupo and real design wheelset (I will probably replace the wheels).

Probably over $2000 the way things have been lately. I don't know why, but they sem to be fetching some good prices since they're no longer available through CC.
