Forgive me if this has been covered, but with all the problems you guys are experiencing, can anyone give an explanation why they didn't catch these problems before the IS came to the states? (driving conditions, manufacturing plants, etc...) Is the IS300 really that different from the 200 or the Altezza? Maybe Im the only one thinking about this but I would think they would catch the problems in the other two models since they came out a while before the IS300.
