But the LS430s aren't really comparable to the current gen Toyota safety systems. The LS430s have dynamic cruise control but they won't bring the car to a complete stop, the dynamic cruise control in the 01-03s is a little weird (and I think it has some reliability problems). And the dynamic cruise control is bundled with the Ultra Luxury package which has a lot of stuff to break (an extra A/C unit for the rear, air suspension, and double thick glass that can fog internally if it cracks).
The Modern Luxury trim cars have the dynamic cruise control without the air suspension, a/c unit, and a few other gizmos but they're really rare.
And I'd be remiss if I didn't mention it, but the 01-03 LS430 is probably the best used car value in America. You can get a decent one for 5k (they'll ask for 7k but tell them to pound sand) and they're unbelievably nice. They're not Avalons, but they drive like every Toyota ever just with more poise and fluidity.
Is there something special about the LS430 air suspension? I own a Town Car with rear air suspension and it is my favorite feature of that car. Parts don't seem to be expensive and there is a large aftermarket. I have been recommending rear air suspensions to others interested in comfortable road trip cars.
It's a volume thing - the LS430 is a relatively rare car, air suspension is a relatively rare option (only available on the top two trip levels), and the replacement parts are only available through lexus. There isn't anyone who rebuilds them or sells them private label.
For the price of 1 air shock replaced at the dealer, you can get an independent mechanic to put the car on conventional suspension and it'll still ride good enough on smaller wheels.
