Ford Crown Victoria: The Lincoln Town Car and Mercury Grand Marquis are based on the same platform. For those just looking for a beater, and don't drive very much, the price of a government issued Crown Vic is the cheapest durable buy you can find on a pound-per-pound basis. Government surplus auction models that haven't seen police duty are tough to beat.

* what do they mean, "don't drive very much"??
