Not just anyone, but everyone can file a claim to the car. In case several claims are made for the same car, the claimant that gets to purchase the car is picked at random.
Not every game or sport has to devolve to angling for loopholes. Sure, get a friend to buy it, never be invited to compete again. Congratulations, you cheated to win a race almost nobody knows or cares about (if people did care so much about winning this race, they wouldn't think twice about "losing" a million bucks by openly over-spending).
