Bait and switch. Premium car advanced reservation with unlimited mileage, morphed into full size with only 400 miles, then .25 cents.
Arrived at counter in Mobile, Al on 3 Aug 2012. Was quickly informed that Movile Airport location had no real premium cars in fleet--best they had in fleet was a Camey. When asked for farthest drive point, the dude pulled out a random cross hatched map which showed our destination out of the "area". Suddenly unlimitedileage became .25 per mile after the first 400.
Reservation for 141 bucks turned into close to 500--btw when made revs full size was "sold out". Beware, have heard about this same scam pulled on many at Dollar/Thrifty counter in Mobile Regional Arpt
