I like the factory leather they have in new ludes here in australia, but my one didn't have that option. Just recently though have added pair of sparco seats, grey retrim of arm rests, brake boot, transmission boot (I saw the thread on the ss boot, and thought it looked awesome, don't care what the haters say

), centre console and floor mats currently being detailed with grey lining too.
oh yeah... and dont forget, whatever you do to your car, it's still your car, so don't pay too much attention to what other people say

especially with the interior, anything you change is going to affect you 100% of the time you drive the car.
