Flew in and out of DCA for a few months straight. Once had a string of Ford Escape, Escape, and Expedition with Mid-size rental agreements. Got tons of Explorers, too. I would say that getting a Taurus there would be abnormality.
The DCA #1 gold dude is super nice, but he definitely plays by the book. If there's a car out there, no SUVs or prestige collection. But otherwise, they are usually pretty generous (at least to me).
Now DFW, on the other hand, is just Taurus galore! I've never seen so many Tauri (sp?) sitting in the same parking lot before. I felt like I was in a Ford plant or something....
