<< The Lexus IS300 has been selling very poorly in the U.S. I doubt they will be introducing any new IS models. >>
And where did you hear that rubbish from? From all accounts that I have seen, the IS300 has been doing well. Otherwise, they wouldn't have added a 5-speed and a 5-door wagon to the lineup. They are also thinking about adding a coupe and convertible version of the IS300.
So either this is just something you made up, or you SHOW me where you hear that sales are poor.
Secondly, the new IS430 looks SWEEEEEEEEEEEEEEEEEEEEET
