...but what parts of the seats exactly are leather?

 

All of mine, as far as I can tell.

I had an RRS with the LUX package and that leather was nicer but I quickly wished I had the regular perforated leather seats, as the pulled-leather on the LUX models cracked extensively after 6-9 years. The rear seats were beautiful still, but required constant conditioning.

Definitely like the regular leather interior better.

Image of the LUX leather on the sport when I sold it, and no I don't have any images of the driver seat - for good reason lol!
