I am planning on purchasing a new silver wrx in the next month. I was wondering what Interior options you recommend i get for the WRX. Keep in mind anything i dont get as an option from subaru, it will probably be a while before i can mod it since i am taking care of exterior first. Is the premium sound package upgrade any good? I dont have the exact list of the options now, but if any of you have any and like or dislike please let me know.
