To me it seems like the Prius C is set up for roof racks with the design of the rain gutters. A few of my friends noticed this also. I am hoping this is the case because I'm nervous about installing a hitch. I really, really want a hitch, bike rack and a small cargo carrier, but after seeing the manual I'm scared to go this route now, maybe in the future I will. Do you Prius C owners think the roof is deigned for a roof rack in mind? I helped my girlfriend with a urban free market this past Sunday, and I had it packed to the brim! I was surprised it held more than I thought, but I would like other options for bikes and gear.
