My buddy wants to sell off one of his bikes but doesn't know what to list it for. I'm horrible at this game, so thought I'd ask here to get a mix of opinions.

59c Scatantte frame in great condition, low miles, black carbon.
Ultegra 6800 groupset
Kinlin 279 hoops/novatec hubs
Deda bars and stem

Thoughts? I guessed around $750.
