My second LS 430, this one trumps the 02 I had easily. The seats are much improved, and near perfect now. Handling is better, though not a Bimmer, it's good. Dependability is perfect. Love the Bluetooth phone, which works flawlessly with my Treo every time. The A/C is the best I've ever known, and the cooled seats are welcome in the desert. Can't get more luxury value for the money, IMO.
Smartaccess system, letting me in and start without a key. Bluetooth as mentioned above, and cooled seats. Rear camera for reverse and park assist.
Jazz up the style a bit, which may happen in 07 from what I've seen. A smaller steering wheel would be welcome, this one is a bit like a bus. More bass in the sound system would be welcome also. The dash and instrument panel are somewhat plain by today's standards, but functional.
