The IS 350 is better than the reviews may appear, actually. I for one enjoy all that techno stuff and I still think the car thinks it's a 911! Very torquey and great handling, along with every possible amenity make this car the best vehicle I've ever owned. HIGHLY recommended.
Styling, powerful 306 HP engine.
Better/more intuitive navigation/voice command system. Speakers could be somewhat better in the Levinson system, too.
