I wonder if this would work at CMH:
Ask them if you can rent from the one-way aisle, because although you booked it as round trip (returning to CMH), your plans "might" change... then they'd let you pick out of that corporate aisle...
I rented from CMH and was on a one-way, and got a nice Jetta (under 5K miles), and another time got a Durango. Local CMH you get - as Mistress Kai said - your choice of Cruze/Malibu color (blech).
