A couple mouldings and an illumination kit for the rear center panel... that's it, finally, after maintaining an inventory of at least 5 uninstalled Z toys (not to be confused with ztoyz) since shortly after I first bought my Z. It feels nice, take it from me. Get those parts installed because you know you'll enjoy them more than sitting in boxes in your house... do it... and don't buy any more parts until you do because you'll never get around to the ones you have ;)
