Be sure to check out the six speed Saab 9-3 Aeros, which has been significantly redesigned this year. It will kill an IS 250. Don't know about an RX-8 but I believe those RX-8s are really low in the torque department. As for reliability... well my Saab just hit 132,000 miles and looks and runs spectacular, although it's a 9-5 not a 9-3.

If you wait a few months the all wheel drive, 280 horse and 295 ft-lb version will be in the United States. It's getting great reviews in Europe.
