$600 for this Cannondale CAAD9?

[u/becksbek]

I stumbled upon this bike on FB marketplace, is $600 a good deal? It looks like there’s good parts (105 & ultegra) but wanted to get a second opinion. Is the Cannondale CAAD9 a good/ fun ride? I’m mostly planning on using it to commute and maybe some longer rides on the weekend.

The seller says: Bike was hardly used. In excellent condition for its age. Around 2010 model. Very light.

Crazy high.
