... removing the model numbers ("325e")? If so, use dental floss or fishing line to saw through the adhesive between the trunk lid and the numerals. Once the numerals are off the car, use mild paint cleaner/polish to clean off any remaining adhesive and smooth out the paint. On some cars, there might be a "325e" outline where the paint hasn't faded along with the rest; on a white car like yours, it's not apt to be noticeable.
