I'll mention another I4 sports car: the Honda S2000. (Yes, I know the torque numbers...
)
Oh, and my wife says when she was a kid, her mom had a 1st gen RX-7, and she always had to lay down in the back. :hehehe:
For the RX-7, I'd suggest asking some questions over in the RX-7 forum. Rotary engines are clearly a very different animal than piston engines. There is a lot of (mis)information about care, maintenance and repair for these cars, and I'd really want to talk to a lot of RX-7 owners before buying one...
