I rent a standard SUV then that is what I want. Sure as a 5* or PC I expect at least an XLT with leather and a few options. But an Eddie Bauer would be nice to expect as well...I dont expect a Expedition or Escalade or H3...
I rent a mid size vehicle or full size then yeah I will take anything that hold 4 people and stuff...But I still expect my upgrade on those.
I am with you, I am not getting my upgrades either...
Do a real test. Rent a F or C class car from both and see what you get...
