Pros: stupid fast. Excellent handling, very predictive and sure footed. Excellent build quality. Comfortable cabin for a sports car. Lexus quiet on smooth pavement. Extremely fast gear changes with manual mode. Powerful brakes. Very well equipped with little nonsense options. Excellent fuel economy for v8. Cons: steering a bit too firm at low speed. Car is a bit heavy and not as tossable as a small sports car. Mark Levinson is mediocre in quality. Ergonomics is not as intuitive as Acura/ Honda. Automatic transmission is a bit sluggish unless switched to manual mode. Loud cabin on rough surface or when under wide open throttle.
416 horses. Super fast transmission (manual mode). Ultra powerful brakes. Build quality. Quiet cabin (at least on smooth pavement).
Audio system ergonomics. More aggressive automatic transmission in sports mode. Reduce weight. Quantitative tire pressure monitor. More rear leg room.
