Well that depends on where you live!!!! I know when I was home ported in Hawaii you had to have every thing that came stock on the car!!!! If you put mods on the car you had to have some perment ( or some thing like that) with you at all times in the car for EVERY thing you change or add that is not stock. Its been three years since I was there, thier is another member here that live there now and he would know the updated details beter than I. To me it was just a way to for them to just get more money (think $20.00 for every single one) for there over rated islands....
