And the winner is: the Lincoln Town Car! It turns out that the reason you are always screaming in traffic at old ladies in Lincoln Town Cars is that it's the #1 car owned by old people. Because they're built like tanks, they'll be around a while even though the Towncar was discontinued last year. The percentages are a bit off; that's the ratio of how many people bought that car, not how many old people own that car. So, that means that nearly every Lincoln Town Car was bought by a senior citizen, so in ten years expect to be able to buy them at estate auctions, with only 10,000 miles on it, for around $500 a piece.
