about to order my first LR4 and am so excited. the windsor leather seats are great- but i can't really tell the difference between the arm rests, dash and door rolls with and without the extended leather pack and need to decide if i should order that option. any advice? 2013 LUX nara bronze/almond/split grain walnut/20 inch 10 split spokewheels/HD pack/sirius/vision assist.
