Jeff- Thats just how Lexus is, they figure out the "optimum" levels of equipment usually in two or three groups and then ship the cars that way. It also varies depending on coast. For instance on the east coast we get ES's one of two ways, a "premium" car like yours without navigation or ML and no rear sunshade and a "Nav/Lev" car like mine, with the nav, the levinson, and the sunshade. You wont find a car equipped any differently anywhere on a dealers lot. No AVS or power pedals availiable on the east coast. Chrome wheels are also incredibly rare.
NOW, on the WEST COAST they ship a model like yours, and the maximum loaded model of the ES including the AVS, the power pedals, and the chrome wheels. You can't buy one over there like mine.
Now, your dealer has two options that they don't always offer you, one they can allocate a car from anywhere in the country. Meaning they can swap a dealer in CA for a car with AVS and power pedals and sell it to you here. OR you can special order any option or color combination you want and they will order it directly from Japan, but you've got to wait 3-4 months. This is a pretty common strategy for foreign carmakers that have long wait times for special models, they lump several levels of popular equipment together. Its actually pretty cool, Lexus doesnt charge for a special order, Mercedes charges $1000. Even if you allocated a car with AVS from CA you'd still have to pay for nav, ML, power pedals, chrome wheels.
On the LS430 they ship 4 ways
-Base model
-Base model with nav/lev
-Modern Luxury with sport package, 18 inch wheels smart access
-Ultra Luxury
And the Ultras are almost impossible to get on the east coast, they had to order my dad's from CA.
Alan, Jeff lives around Washington DC, he and I bought our cars from the same saleswoman.
Brian, I believe the only way is to buy the manual or have someone scan the pages for you, I don't believe they're avail. anywhere online.
