Hmmm... I was about to say Toyota Avalon, but someone picked that already. Do they still make the Toyota Altezza RS200? If not, then I nominate the base Chrysler 300, since I think that is the only one in the price range...
Having driven a 2005 Commodore SS, I'm glad it has been nominated.
This car should stand a good chance of winning, even over some European cars.
I love this car! (Well, not literally.)
