National at LGA let me take a Challenger one-way to Maine last year on a 1-2 Free day. I was surprised they'd allow such a car to be taken away. But no, the greeter actually pointed it out to me on the EA, when I said I didn't want the minivans she showed me on the aisle. I re-confirmed it's okay to take this car one-way to Maine. She said "yeah" and seemed puzzled that I asked. Maybe FL locations have different ideas.
