I still have my teal/magenta 660. I was a great entry level race bike. Ultegra group and the aero rims were nice. I upgraded to a Colnago after a few seasons of racing but I still have the Trek. Hard to part with a first "serious" bike. Didn't think it was worth much...but now...hummm....the color was the second option and not as many were produced....RARE!! $$$$$!!! lol
