I dont know I have always been a fan of Satin Black. As far as the going to NA and then its not worth the $$ to get it back to a TT. after all the work you have into it the body seems to be in a decent shape now. not sure about the interior, but I wouldnt pay insurance for a TT and drive a NA all day. You did an outstanding job though who ever owned that car before you should not ever be allowed to own a Z again.
