Rusty,
    I was thinking about buying a 3rd Gen, but opted for a 300ZX Twin Turbo
for that reason. The Nissans go through turbos (same Airesearch T25, BTW) at
about 100,000 mi (mine have already been replaced), but the engine itself is
bulletproof. I still like the looks of the RX-7 better.  Mike C
