No way in hell this bike is worth $4500

Why would you buy that when you can buy a brand new, modern bike.
It's worth whatever somebody is prepared to pay, I guess. If it is absolutely brand new then I think I'd approach Cannondale and see if they wanted it for a museum, or the dealer network to see if anyone wanted it for their shop. A mate bought a hardly-used Raven off a colleague a few months ago for £500 (he'd bought it new, then hung it on his wall for the last 20 years). My mate was using it last weekend at Swinley, actually - it's hilarious how much respect and attention it gets from anyone 30+.
Edit: this is it.
