Kim Kardashian shops for luxury cars the same way most of us shop for groceries. Even during her pregnancy she just can’t help herself. Not sure why she always seems to constantly be buying a new car, but hey, it’s her money, her decisions. The best thing about this clip of her shopping for a new ride is how she casually throws on “Mercy” while sitting in the Lambo. “Lamborghini Mercy, Your chick she so thirsty”! Check out the clip after the jump.
