In Miami — a freeway city where flash is all that matters — your car is everything. Drive up to a club in a vehicle that costs more than the average two-family house and you'll be shocked at how deferential everybody becomes, from the valet kid to the bouncer to the vampire at the bar with fake boobs and money-symbol eyeballs. Sure, you work at Denny's and drive a dented 1992 Corolla, but that's what those pre-approved plastic things you get in the mail are for: To spend money you ain't got to be somebody you are not. There are tons of exotic-car-rental spots in Miami, but most of them are unlicensed, fly-by-night operations that should be avoided like a streetside game of three-card monte. That said, there are a few legitimate rental businesses. Our favorite is American, which has its main office by Miami International Airport. You'll probably be berated by the wise-cracking Lamborghini Nazi at the front desk, but the place stocks more than 100 luxury vehicles. The experience will cost you from $899 a day for a Porsche Panamera to $2,200 a day for a Ferrari, and yes, it's shallow as hell — but we're guessing there's a reason you don't live someplace classy like Vancouver or San Francisco.
