Not sure about Cancun, but I recently returned from Puerto Vallarta
and all of the rentals I saw were mostly Nissans, with other Japanese/
Korean makes, but I didn't see any Beetles. Maybe some of the
smaller, local companies might have one.
Yeah, no luck in Cancun. They had one at the budget car rental that I
went through, but they said it was too old to rent out anymore. I did
find a place in Cozumel that seems to still rent them though

Golf anyway and that was still fun :)
