I was wondering, does anyone know if the 2013 Prius C has holes in the roof already set up for a roof rack, specifically, the rhino rack ditch mount rack? Vortex 2500 Ditch Mount Black 2 Bar Roof Rack | Rhino-Rack
looking at the video on the etrailer.com site, it looks like it's not actually bolted to the roof as i thought. it's still a clamp mount: Roof Rack for 2013 Toyota Prius c | etrailer.com
