How do Toyota vehicle sponsorships work - do racers own the vehicles?

99% of the time, Toyota uses an 'internal lease' where the driver doesn't pay anything. The vehicle is leased to the driver's company, team, or LLC as part of the sponsorship. When the year is up, the driver gets first option to buy it at a mileage-discounted rate. Many drivers, their relatives, or team owners end up purchasing the vehicles. This also extends to family members - Toyota wants sponsored drivers and their families driving their products.
