When you earn a lot, it's tempting to spend a lot. And a lot of high-earning professional athletes do: NFL star Drew Brees and soccer icon Cristiano Ronaldo both own multimillion-dollar sports cars.

But not every rich athlete spends millions on fancy rides. Quarterback Kirk Cousins drives a dented GMC Savana passenger van that he bought from his grandma for $5,000. Dallas Cowboys running back Alfred Morris still drives a 26-year-old Mazda 626 sedan that he bought for $2.
