for every surviving 240sx twenty years from now (its only 6-7 years until 240sx's start getting classic plates
) there are going to be tons of former owners who generally all had a positive experience and like the car, and lots will miss um (like many former s-chassis owners do) nostalgia will definitely kick in for some of them enough to want another.
as to the argument trying to paralleling top end muscle cars to s chassis, in the u.s. theres a chance that imported silvias and 180sx could be worth big(ger) bucks due to the scarcity and reputation / almost legend of those cars).
motorex imported r32s and r34s are definately going to be worth quite a bit, call those the shelby cobras/shelby mustangs of the nissan future classic car family.. while we're at it silvias/180sx's can be boss429's and mach1's...
i dont agree with that muscle car argument but there is some validity to it
we're all speculators of the future classic car market right now, lets not get too opinionated and start bashing the hell outta each other, no opinion can be proven right for a few more years, so chill fighting soo much about it
