After seeing this thread, I went through some Japan forums
to see if anyone was talking about it. All they're saying is
that the Trueno is sold out practically everywhere and that it's
very hard to come by compared to the NSX-R and the Pitworks.

Hopefully they're not planning to discontinue the car, but if they
are, I would suspect it's because they're going to replace it
with something else. Maybe a Trueno with racing wheels AND
lights! (I wish)
