Just returned a Chrysler 300 Touring today (booked a Premium) - not sure why you can't book a Luxury since there was at least 6 Cadillacs all lined up.
Didn't really look at EA/ES at pickup but on the return Wed 1PM noticed a lot of minivans and Impalas in EA. ES had some 300s, Suburbans

, Fullsize pickups, and one Honda Accord.
