Seriously - you have NO idea what skylines are worth do you.
As has been said, you get what you pay for. Anyone who believes that an R33 GTR should be commonly had for low 30's even for a 1995 model is misguided. I have seen them all before. You only need to look at the price the cars cost from japan, an absolute shit heap R33 GTR with over 100k on the clock at low to mid $30's straight out of Japan is regarded as a bargain.
Im not denying that you see some GTR's particularly in Melbourne being sold stupidly cheap, but there is ALWAYS a reason. Granted some buyers pickup bargains due to vehicle owners being desperate to sell - thats the luck of the draw.
And as for your statement about anything over $25k for a GTST being "TO" much - what complete garbage.
