First, FYI, rentals outside the USA do NOT earn any credit towards free days or Executive status when renting outside the USA, which sucks. So as a result I normally have rented from Europecar or AutoEurope as the deals I've got there are generally much better than I've been able to get from renting directly from National, Avis, Hertz etc (my experience, most of my rentals are during shoulder/off season), but sometimes a better deal can be located. Had a Ford Mondeo Estate wagon rented, they were out of when I arrived. So they put us in a Vauxhall Zafira minivan (as well as threw in GPS). Minivan was a nice ride for us & worked out well as my older parents were able to get in/out of the van easier than the wagon. Sorry I can't recall exact figure but we rented in EDI & dropped off at LHR, fee was quite reasonable !!
