I remember when they brought that concept out. Every damn Nissan fanatics jaw dropped.
rumor has it they decide not to actually produce the car for two reasons and I would guess a third.
First two reasons are the car was going to cost in 70-80K range here in the states. Territory, Nissan had never explored in U.S. Also remember this was pre NSX. Also the NSX flopped miserably in sales for the first couple of years it was out. hell I remember being able to get a 92 NSX from my friends brother who worked at a Porsche dealer in Palo Alto for $25k wholesale.(I knew I should have bought that car <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='

Second reason , they were still building and selling 300zx Z31's
. Even the Skyline at that point in time had not fully reached Supercar status i.e. this was pre R32.
Third and this is were rumor sets in . It was to close to the design of several existings Ferrari's and they would have been sued by Ferrari and don't think Ferrari might not have done that. Ferrari, was sue happy in the 80's after Enzo died. They actually did sue a Ferrari GTO knock off company that was basing dead look alike GTO's on early Z cars.
who knows, but at this time it does not matter that was over ten years ago.
