FWIW, I bought a discounted 2013 CAAD10 105 last fall and it's just awesome. I rode a SuperSix and a CAAD8 when shopping, and it was an easy decision for me. I put a new saddle (Specialized Romin Evo Expert) and tires (Conti GP4000S, 25mm) on it, and it's way more comfortable now, and, as a result, way faster. I'd hold out for the 10 if you can.
