I'm sure with a quick search you can come up with pictures of the complete leather interior vs. sport / standard interior.
I prefer the complete leather interior where everything is either wood, leather, or Alcantara.
It really comes down to what you want. The non-complete leather interior looks sportier with the Aluminum trim and two-tone seats. However when I bought I figured if I was going to spend all this money it should have dead cow on everything I could touch. Plus, I really like the look of the complete leather caramel interior.
