Kim Kardashian is one lucky girl who definitely has the need for speed!

In one day, the bootylicious babe was able to drive her beau Kanye West's $500,000 silver Mercedes McLaren AND her $300,000 white Ferrari! Both rides were sitting pretty in the reality star's Beverly Hills driveway.

Just yesterday, Kim took Kanye's pricey ride to Barry's Boot Camp for an afternoon workout. Let's hope she didn't get those expensive leather seats too sweaty.
