Car hire in Portugal & drop off in Spain?

HI, does anyone know of a car hire company that allows you pick up in one country and drop off in another?
looking to do a road trip through Portugal & Spain

thanks

as far as I know hertz allows this

exaclty,
only the majpr car companies.

it works out v expensive.
the local companies in faro airport do not charge extra for driving in spain, but you will have to leave it back. the big boys will charge you for second drop-off, spain insurance etc etc. it will be expensive.
