IMO, Caramel looks best with the white exterior. The really nice thing about the Caramel or Ecru (which I have) is that it is a two-tone interior. Whereas the black interior (leather or Nuluxe) is only black, you get black panels on the dorr and with the black dash top on the lighter colored interior, it looks richer in my opinion. Caramel would have been my first choice interior but like you, I took what the dealer had. I too wanted LED lowbeams...however, I did get NAV and happy I did. Haven't used the NAV itself yet but like the display for everything else. I'm not sure what your codes make your car out to be but if you can, add the light up door sills. I went out a couple of times with other couples and my wife and people always comment on those...they do look great at night.
