Odd thing about the -33962/33963 - until roughly a year ago, the Lexus descriptions in the above-linked site were indistinguishable bar their respective stereo systems.
Couple things there are a diff between ES hybrid and non hybrid.
3681 has ldw, antenna and rain/humidity sensor non hybrid
there is also an option for Panoramic roof
3682 has antenna , heat, rain with humidity sensor
