Until recently I had a Caad5 105 which I sold to my brother - bought it a year earlier for $500 on CL. I ride a Caad8 Optimo R5000 now with DuraAce. As nice as the Caad5 was, the Caad8 is even nicer. I bought a second Caad8, 2006 frame, in pristine condition last fall on eBay for $275 and built it up with Campy. Both ride beautifully - I have no desire to "move up".
