I've got 93,000 on my '99 Mystique LS, Duratec and ATX. Absolutely no problems, followed Ford's maintenance schedule (severe service) and with the exception of fluid and filter changes, only replacement parts have been sparkplugs at 60K and one set of tires at 40K. Looks like I'll get 60K out of the second set of tires (Michelin Rain Force). I commute 100 miles a day to work, so the Interstate miles are really easy on the car. My last car (a BMW 325) was still running like new at 251K when I traded it for the Mystique.
