Zetec has lower sportier suspension, bit harsh on everyday driving but theres really nothing much in it when it comes to handling with the LX, bit more roll but nothing to write home about, smoother ride though (having driven my mates 03 zetec for 2 months before i bought my 02 LX a few months later, for all the experts who've never actually driven the cars in question
) MK1 LX has the climate pack as standard while it was optional with the zetec as said before. By the suspension height and wheels i'd say that was an LX as well.
