^^ correct. ZHP's were only packaged 330's. There is a tread on it in this subforum stickied at the top. Only way you saw a 325 ZHP was someone with a 325 who got the ZHP appearance package kit installed on it. I have the M tech kit at home right now waiting to be installed, but by no means is my car a ZHP.
I haven't seen a ZHP or M-Performance Package 330 for sale in Ontario for a good price without over 80,000km or more in some time.
