Thats similar price to what a CAAD10 would go. Which is also a risk buying used given how Cannondale has gone to lengths to make it light. System Six is a risk on another level .. all that Caad10 risk (BB30, Thin wall alu) plus alu carbon bond.
I have bought CAAD10 frameset in the past and sold one too used but it was to/from people I know. £250 down the drain vs £700 (or whatever it is) for 'lifetime' peace of mind .. I know what I'd do. Same goes for ANY carbon frames too if not more.
