It looks like the S30 is testing the viability of the US collectable car market for Japanese cars now. If prices for these keep going up at a rapid rate, the Z32tt is probably not far behind. With a little more than 18,000 Z32tt's (and far fewer convertibles) sold in the US, prices should go up. They sold a greater number of Camaro Z28's in 1969 alone. They sold tons of S30s in the US.
