Hmm yeah I wonder what goes on in deciding or how much discretion managers outsource. I just read through threads for a number of different airports and it seems like some including LAX have BMWs, Mercedes etc that do show up sometimes on ES while YYZ seems to never have any premium like cars on ES.

I wonder why other car rentals have not allowed for this level of choice or why some city downtown branches couldn't do something similar like at least give a few options to choose from. I hate being that customer that asks the counter at a downtown branch asking what other cars they have and I have always been curious how the rental agent chooses which car to assign to you in those cases too
