Most passengers I fly with, who are 6'6", generally sit down when they are in the aircraft, so standing room of 7'1" is not really an issue.
Additionally a distance of less than 300 miles from Algiers to Valencia, the conventional wisdom is that a Turbo Prop would be a better bet.
Indeed if you are heading further into the country, an aircraft like a King Air or PC12 would be more flexible on an un-prepared strip.
An older aircraft my seem cheaper, however if you are not on an engine program, you could find that your $2.5mil will be sitting around waiting for a very very expensive part or inspection.
Every few months somebody comes on here and asks us what we think as pilots, engineers, brokers and businessmen, indeed generally a combination of at least 2 of these. When the situation is explained many don't agree.
However there will always be people out there who know everything while there are even more who would be very keen to relieve the naive of their funds for an old dog of an aircraft. (see the Robert Weaver thread).
People are more than willing to help, indeed, you will find everything that you are looking for on this forum.
