Let's bring this around to something that the Skyline fanboys can (hopefully) comprehend:
We're talking about an R32, right? Specifically, a 1989 Skyline. OK.
Between 1989 and 1994, 43,934 Skylines were built. That's 6 years. Let's ASSUME that an equal number were built each year. That leaves 7,322 Skylines to fight over.
IN COMPARISON, Nissan built 68,118 240sx's in 1989.
That's 9.3 TIMES as many 240sx's as Skylines.
25 years later, can you find a nice 1989 240sx? Maybe one that's been in the southwest its whole life. I don't see many at all.
But wait - there's more: Japan is an island country, with a lot of rain, and is surrounded by saltwater. You think those cars survived without rusting?
Let's also remember that, unlike the US, Japanese drivers have NO incentive to keep and maintain a car for 25 years. It gets MORE expensive, not less.
The only real hope in finding a GOOD R32 is to find one that was stored, or exported to Australia / New Zealand, or maybe Canada (but they rusted too). Good luck with that. You'd have better luck finding a Hemi 'Cuda in a barn with 10K miles.
