my zetec still ran awesome at 133,00 miles and its been ragged on all day long everyday for 60,000 miles, and i never had to do a whole lot to the engine besides the timing belt and wires and plugs and a vct solenoid, wish the CD4E liked me more though...lol...and you cant say i drive like an a$$hole either because thats what u have to do to keep up with traffic with the ATX zetec!
