just updating you. my '97 mystique zetec in portofino blue (very cool color) now has about 98000 miles, and its still got the stock belt on it. still noisy at startup due to the cover rub, but still gets anywhere from 26-31 mpg depending where driven. just added a can of restore at last oil change. it doesn't burn a drop of oil either. at 100K i will change the belt, plugs, wires, rotor or whatever it has, tranny fluid, maybe a coolant flush. i love her. a downright cheap ride that's one of the most reliable cars i've owned. will cruise at 75 or 100 if called upon. good luck guys
