4. Gwen Stefani’s Rolls-Royce Wraith – $400,000
Gwen Stefani isn’t playing around when it comes to splashing the cash on a nice luxury vehicle. She drives a dark blue Rolls-Royce Wraith that has a V-12 engine and 624 horsepower. The car is so awesome that it has an “on-board valet,” whatever that means. The car is sweet and sassy, just like Gwen!
