Trust me there are cars you dont want to pull the engine out more then once, and a Z car isnt one you need to worry about. It's not bad at all.
Im kinda in the same boat, I have basicly a turbo car minus the shell and rust and rims/tires, and Im about to compression test it and all that when I get home (its in ohio im in florida, sanford (anybody with a cool Z car around here?)) and see where I stand.
I might know where a 260z is cheap so hopefully its not a rust bucket, and I can pick it up...
