I believe this is what is different with the accent package: Orange accents on front and rear seats, the front and rear door inserts, above the glove box insert and the sliding cover by the shifter; color stitching on dash, center console, front and rear seats, door arm rests, steering wheel and shifter; alcantara inserts on front and rear seats; and as mentioned brushed aluminum on the dash and center console areas and steering wheel; and the smooth leather around the steering wheel.
It's awesome!
Yup, and if you add CF with the accent package, you keep all of the accent package options and replace only the orange honey comb parts for CF pieces.
