get your self some dentel floss then simply slide it behind the decals and use a sawing motion to remove, thats for the volvo and 850 simbols as for actual stickers from dealers and what not, your best off getting either some sticker shock, or nail polish remover, either way just get the sticker really wet let it sit for a few min then peal off with your finger nail, wile being carful not to scratch the paint. when your done just grab some wax and polish away anything that was left behind!!
