I wouldn't be that quick to pass this by: is it genuinely 'new' old stock (i.e. not a demo etc), is it in fact a full-carbon 7.9FX, and is your bike shop a Trek dealer? If yes to all, then 1699 is high-ish, but not outrageous, and there might be room to negotiate? The full-carbon FX is now (2012) discontinued, I think (?), so if you love/want the bike and it's the right size, might be worth a closer look?
