> With National I get my pick of any car on the lot (and with a corp discount code, usually around $30-40/day all-in).

When I fly and need a car I also use National to avoid the hassle of long lines and forms, just walk to the lot, pick a car get in and go, zero hassle. But this only works at airport locations so it is not a solution for the local use being discussed.

With local rentals I've never managed to get out in less than ~45 minutes of paperwork and waiting, it's a huge hassle.

Also as you'll know, with the Emerald Aisle the minimum class is midsize so there's a price premium for the convenience. Just got back from a trip yesterday using a National rental, $644 all-in for 6 days for the smallest car I can get on Emerald Aisle. Over $100/day. You must have a nice corp discount.
