You shouldn't rely on the list on the Hertz web site. There are only specific cars in the Premium class. They include the Mercury Grand Marquis, Ford Crown Victoria, and Buick Lucerne. I don't have a full list but I know those are definitely included. So expect to get one of those cars, or if they're not available you'll be offered a free upgrade to a better car (Lincoln Town Car, Kia Amanti, Toyota Avalon). Szymon
