Key: Cupholder reliably holds a liter bottle.
So far, I've come across those pathetic, throwaway quality jobbies at Advanced Auto and such to fit that bill. They work great, and at 50 cents each (a quarter on a shelf clearance a while ago) if one gets snagged, bent, snapped, squashed, or otherwise mangled or destroyed (or stolen? times are tough!),
who cares?
