You may consider just moving to Japan!
Over here you can get a used skyline GT-R:
R34 for $50,000 - $32,000
R33 for $25,000 - $15,000
R32 for $18,000 - $6,000
The only problem I'm facing now is that the R33 and R32 GT-Rs are considdered "Yanki" cars or cars owned by punk kids. Its a real stigma over here. The R34s are still pricey enough where the kids don't own them. But you just don't see any adults driving R33s or R32 GT-Rs. I'm kind of apprehensive about buying an R33 as my neighbors and friends may banish me!
I've been eyeing the Toyota Alteza (Lexus IS 300). You can get a 3 year old Z model for under $10,000. They are nice, but man there is this Blue R33 GT-R I see everyday on the way to work. Man is it sweet!
Oh well. Decissions, decissions!
