After reviewing all the competition from Japan and Germany the IS 350 won. From a value standpoint it is far, far less expensive when you add all the options that are standard. But more important the car is built to the highest standards in this category with a wonderful 306hp engine that rockets this car effortlessly to speeds well over the limit. Mine has the Sport Package which includes a firmer suspension and larger wheels and the car sticks like glue in the corners although it gets a bit unsettled in the bumpy stuff. The Navigation w/Mark Levinson stereo is superb and highly recommended. I understand the ML system is not usually ordered by the dealers, but look around to find one.
Overall high level of execution. Mark Levinson stereo/DVD system, and the optional XM satellite radio and MP3 input make for a wide array of listening possibilities on long trips. Engine performance is outstanding and offers plenty of power and flexibility. Absolutely top drawer powerplant.
A bit more work on the overall suspension package is in order in my opinion. It can be a bit jittery in some situations. And the power steering is a bit overboosted and 'light', I'd like a bit more feedback to know what the front end is doing. Nothing else needs attention from what I see.
