i have heard from a lexus dealer that when lexus adds coach or something else to one of its models, that that model will soon be redesigned like the ES, LS 400, RX. I know that the IS will so change due to a coupe version, V6, and possibly a convertible, but will the GS model the redesigned cause it bee out for 6 years already with few changes made to it. the sportdesigned edition with the saddle leather is really nice. to me it adds more class than it already has. anyways i was just wondering if the IS 330 or 430 whichever model is coming out, will that be the last year for that IS generation?
