The LS 430 retails for $54,405. That figure buys a premium, full-size sedan loaded with sophisticated mechanical equipment, extensive safety systems and luxurious appointments. The sole engine, a four-cam 4.3-liter aluminum V8, produces 290 horsepower and mates to an electronically controlled five-speed automatic transmission.
Opt for the aptly named Ultra Luxury Selection ($12,485) and the factory adds a list of hardware that reads like science fiction: laser-guided cruise control, a sonar-based parking guide, a navigation system that triangulates by satellites and coordinates with a DVD-powered data base, and an adaptive electronically controlled suspension that rides on air rather than springs. A fan inside the front seats circulates either heated or chilled air. Rear-seat passengers relax with their own air conditioning and air filtration system; plus heated seats, with electric seatback adjustment, memory control and a power lumbar massager. A power-operated sunscreen shades the backs of rear passenger's necks. Side-window screens are provided, but must be pulled down manually.
