The LS430 is one of the best-scoring luxury sedans we've tested. The cabin is very quiet and comfortable and the controls are intuitive to use. The powertrain is especially refined. The rear-seat area is roomy and very well equipped, especially compared to others in this class. Handling is sound. Overall, the LS430 exhibits a plush, luxurious driving experience, but lacks the exciting feel of a sports sedan -- which it is not.
