We bought a '99 LX used in 2001 with 17,000 miles, paid $9,500. Pretty base model, no power locks, no power seat, steel wheels, base V6. It does have the AX4N transmission, the same one that goes in the Duratech powered cars, should last longer then the car - much better then the AX4S that normally goes in the Vulcan powered cars. Driven the car 66,000 miles with two repairs; the wiper washer pump and an exhaust sensor - total about $150. New rotors on the front at 60K, trannie flush at 40K. Paint looks good, interior is in good shape too even with two kids tearing it up. A good rock solid car for the money; bought my mom one just like it a month later for even less.
Low maintenance, fair mileage (24 mpg every tank since bought). Have never added a quart of oil between changes.
Low power, some wind noise, uninspired looks. Front leg room is somewhat limited - I'm 6' tall and it's a little cramped. Don't know how they sell any Tauruses new, they lose half their value in a year, but if you buy used it's a steal.
