Got there last Friday - lots of choices, mostly hum-drum options. Most notable cars I saw were a Chrysler 300S, v6 camaros/challengers/mustangs, full size SUVs, nissan maximas, and a Cadillac XT5.
Asked the attendant if I could take a muscle car with a V8 - he pointed me to a white loaded Camaro SS and said "feel free to take that one" - WOW what an amazing car. 455 horsepower 6.2L V8 sports car for the price of a midsize sedan. Gotta love national!
