I agree with IanS. I think the "gay" phase of the 240sx expired decades ago. I am surprised how many phases 240sx went thru over the years. Here's an unofficial timeline IMHO:
When the 240SX was introduced in the US in '89, it was briefly considered very cool. It was not ground breaking, but it was RWD, sporty, fun to drive, pleasant to the eye, inexpensive to buy, insure, maintain, repair, easy on gas, plus it was reliable. A great value sporty coupe. That coolness ended quickly. It then entered the "chick" car era as it was suddenly proclaimed underpowered despite actually having average power amongst it's competition of the day. Go figure. That eventually morphed into it becoming a "gay" car, especially if it had a (gasp) automatic transmission. They remained almost cool if you had a 5 speed and did an SR or LS-1 engine swap. That period seemed to fade once they fully depreciated to become affordable by kids Then the "Rodney Dangerfield" era began (as in "no respect at all") as kids began modifying them en mass, treating many rather badly, including slapping free car part stickers over rust spots and installing unpainted cheapie body kits and non-functional-look-at- me deck spoilers. Then, when American drifters discovered their charms, things began to change again. 240's were now cool again but only if you drifted them. I think every owner will tell you they were asked multiple times if they drifted their 240's. A drift tax even formed, jump starting values as they got more popular again. So many got destroyed by the drifters, and of course, inexperienced yet enthusiastic male kid ownership attempting to drift, made values go up even more especially stock ones. Fast forward a few more years, and more people have begun trying to restore them, despite time/rust having taken its toll, Now they've become money pits to restore, despite enjoying a long, solid reputation for reliability. Well, unless you start with an even more rare non-abused non-rusty original owner, garage kept, stock "holy grail" donor car. At this point, given it's crazy timeline since its US introduction, I think one can easily argue they've somehow become a lower level collectible.
