Placed on the open road, the LS 430 feels like its riding on a layer of emollient, gliding along upon a frictionless lubricant. This is ostensibly done through the use of a sophisticated double wishbone suspension system front and back. While it cant compete in terms of sheer athleticism with a BMW 7 Series, the LS, particularly when equipped with the optional sport-tuned suspension, remains surprisingly stable on twisty roads., , As expected from a super luxury sedan, the interior is incredibly comfortable and roomy. The driver seat offers 14-way power adjustment with lumbar control and a power height-adjustor seatbelt, which is easy to insert into its slot thanks to an illuminated buckle. Beautiful Optitron gauges provide great gauge-cluster visibility, and the premium-quality California walnut wood trim and delectable leather will mollify even the most discerning of tastes. Open the trunklid, supported by gas-strut hinges, to reveal a cavernous 20-cubic-foot trunk. The load floor may not be flat, but you cant argue with the amount of storage space. And you get a standard ski pass-through, which is optional in some other luxury cars.
