I empathize w/ you completely. My Z is also a '90 - had her for almost 11 yrs now. I don't know what I would do if that happened to my baby. All I know is it seems like you're the kind of guy who will bounce back w/ flying colors. Anyone who had a Z like that must truly appreciate the beauty that these cars hold. That alone tells me that this is not nearly the end for you my friend.
Good luck with everything, and get back up swingin'
