Aaah - that makes sense. Just too many items would have to be added and therefore can't be added by the dealer. Learned something new again....my car came with it ...Option package # 23 (SAP) is $3,645.00 MSRP.
Since SAP packages only come in Saddle Brown Leather and Keyless Access & Start (to name a few), these things can not be upgraded after the fact---technically maybe but it wouldnt make sense.
Brilliant Brown Pearl was a limited time color in the SAP---I believe they stopped production a few months ago. I ran into my first Brilliant Brown Pearl in the SLC Valley last weekend---rare color combo and the first I had seen since purchasing in July.
I really like the keyless access button---never remove my keys from my jacket or pockets for the most part.
