I wasn't trying to say the car was an investment, I was saying he would be smart to finance the car because it would be a better use of money, and could possibly end up paying little to no intrest on it, depending on the return of his other investment. It's called leverage, borrowing money is a good thing, as contrary to popular belief. Why do you think real estate is such a good investment? Becuase of leverage, it requires little initial investment, so you can use the money you would have payed on the house in other areas.
