First, I live in S.Cal and when I see a Z32 "it turns my head" because there are not too many of us out there.
In Peters spot, He has a Stage XV+ TT ZX in Canada. His Key is definitely a 300ZX key (looks). They know it goes to a 300ZX. Would you want to take the chance. I have to say I have not driven in Montreal, Canada but would lay odds that there are not many (if any) Z in that area, just like mine.
