Am I the only one mislead and disappointed by this thread's title - j/k.
Rack: OEM Mazda 1st Gen with wind diffusers.
Carriers: Honda CRV OEM rack (unbranded Thule Big Mouth) and universal Thule Big Mouth. Both converted to use the express adapter so they come on/off with a simple flip of 3 toggles (yes, has locks). I'm planning on demoting these to the Fit and getting a hitch for the Mz5.
