RX8 - unique, classic styling in a gorgeous package. Gotta love the renesis....you don't? Well F you then.
350Z - alright, another iconic nameplate, but falls short of living up to it's reputation. When I think of "Z" I think twin turbo terror. The new Z is just not all that great. I would think a factory Z should include a TT model...conversly, I don't think the RX8 needs the twin turbo as the motor is brand new and will get FI with more time.
IS300 - really? is this even a comparo? The IS300 is the ultimate mommy car. My wife likes 'em, nuff said. Too slow, too little power, too high a price tag. I'd personally rather have something else but if I was forced to own a Toyota this would be the one.
