One of the first signs you're a wealthy traveler like Khloe Kardashian? Get seen in a sweet ride as you cruise around town. While you may not want a velvet-cloaked Range Rover, you can rent high-end cars (think Porsches, Mercedes and even Ferrari) from rental agencies like Enterprise and Hertz. True, these luxury cruisers come with a hefty price tag, but split the cost with your squad and that Lamborghini will start costing you about as much as a compact sedan.
