What I value the most is being able to use the Emerald Reserve service for any car for my reward days -- I usually get Suburbans or Expeditions for family vacations, something you can't always count on being available via the Executive Aisle. I should point out that I don't believe I have ever been turned down -- when the upgraded vehicle I want is actually available -- when asking for an upgrade to an SUV at a counter service location or for an SUV when renting at an Executive Aisle location where there are SUV's available but not actually in the Aisle. But I don't know that this is necessarily a result of Executive Elite status; I might get the same treatment as an Exec.
