Gonna be renting from here next month. Looking for some recommendations as this will be my third National experience, my previous 2 haven't been all that great (both prior were at OAK). I don't rent cars all too often... Have EE

First time rented "Luxury car" and ended being told to pick from the aisle, was pretty annoyed as I payed more for luxury but ended up with an aisle car...
Second time did minimum for aisle, ended up with a camry where I could have just rented a camry for much cheaper from avis, and they didn't allow me to add my father as an additional driver

So what can I expect with LCAR, can I pick from the premier aisle or will it be whatever they pick out for me (better not be a 300c or infinit) or should I just book whatever full size car thats cheaper and hope from the aisle I can upgrade. Or I might just peak at what they have/offer and back out and go to avis instead with a seperate booking

(trying to do a 1 week rental) getting quotes from 430-470s using autoslash

Will my third time be a charm or the final straw
