where is it best to upgrade the car hire. the car hire site attached to the forum is one of , if not the best place around to hire vehicles from, but sometimes you get them in with a deal already. so,

as an example, the difference between a compact car with full ins to say a convertible for the week is about £70 or say $130.

i know the theorem of,' wait cos you may get an upgrade if they havent got what you ordered', but does anyone know the actual costs at orlando or miami etc
