1: Limited Production Runs
Celebrities will scour the world for a limited-run vehicle in demand. Take Birdman, for instance, the first owner of the Bugatti Veyron. The car was at one point the most expensive car in the world, and Birdman was the first owner. The Veyron had many unique features and the car was far from being street legal.
This is just one example of opulence and rarity, which many celebs seem to go for from time to time. The limited production run of the vehicle made it a stand out choice for most celebrities.
