I got a great deal a while back on a ZT 350 and 302 and have been trying to find out more info on the 302. Lots of searching on here and Google, but I can't find any info on how long or how many were made? I see lots of interest in them and not many available, just curious how many are out there. And mine is a low serial '06, wondering how long they were made after that. Anybody know? Thanks!
