The Lexus LX 470 returned unchanged for 1999. The LX had been fitted with a larger engine for 1998, but all that was added for this year was an optional Nakamichi stereo system. The luxury SUV now had a smaller counterpart, the RX 300, a crossover between a sport utility and luxury car pioneered by Lexus. While the RX sold much better than the LX 470, the larger SUV was the true off-road Lexus, if there is such a thing. In many many respects, the LX 470 was fit for such travel. It featured a three-level adjustable height control which could raise or lower the body from optimal off-road visibility down to an easy entrance and exit height. Regardless of the setting, the under carriage ground clearance does not change. The LX also features a 64-setting variable shock absorber system, which can be tailored to a variety of driver preferences and road conditions.

The LX featured the same 4.7 Liter V-8 which was new the previous year. The big V-8 had 230 horsepower and 295 lb-ft of torque. At 13/16 mpg, the LX 470 fell within the common fuel efficiency range for large SUVs.

Drivers love the smooth and steady ride of the LX 470. Despite its monstrous bulk and appearance, it has the attributes of a Lexus interwoven throughout. The interior is spacious, luxurious, and functional. Despite its size, drivers claim that everything is easily within reach. Interior comfort and a refined ride are enough for most drivers, but frequent complaints include a lack of pick-up and its off road limitations. Those expecting a SUV ready to travel anywhere were disappointed that only a limited-slip rear differential is offered.
