thats a real tough question man, my insurance agent tells me R33 turbos go for 9k that's why i listed the red book price of a turbo non turbo skylines always go for less even if it has very rare paint that may make it even more undesirable because of having to match paints (i realise you supplied the paint code)
most of the cars on car sales are dreamers
as someone said earlier its worth what someone wants to pay for it
