I suggest spending the money on a nice mole skin hat, or a purple velvet hat. Alternatively just don't spend the money at all.
Also, as you say, you are undecided. As a human that goes outdoors like many here you will no doubt have seen some cars with decals on them. Mostly small, old and, dare I say, rubbish cars. What are your thoughts when you see these? Do you think the decals improve the worsen the look? FReal questions, btw.
