How much was this option? For the ones that have it, do you think it's worth the price?

 

it comes with the performance package, you can check on the lexus website how much it is.

as for whether or not its worth it: the package is basically a fully loaded package with a lot of options, except for nav, mark levinson, and the dvd player in the back. i dont think its absolutely necessary, though it is nice to have the car lower when you turn off the engine. something that really bothers me is that it takes a long time for the car to raise, and while it does so, there is a loud whining noise from the air suspension module in the back of the car. kinda noisy, kinda embarassing with passengers
