RL's cabin seats five in comfort, and interior dimensions are competitive with the LS 430 and Mercedes E-Class. The front seats are firm enough for good support, but never hard on the backside. Computer-designed seat springs dampen vibration. There's adequate rear headroom. Rear passengers can adjust the register on the back of the center console to direct airflow toward their feet or face. A pass-through portal to the trunk accommodates long items such as skis.

All amenities are there, including an automatic day/night rear-view mirror and driver-position memory that links the seat, steering wheel and side mirrors. The driver looks at electroluminescent gauges that are crisp and easy to read, even in bright sunlight. Switches are easy to find and adjust.
