Back in high school (mid 80s) my dad had a Volvo GL sedan as a company car. For some reason or other he felt he had to add a custom touch, so one day he pulled the grille off and rattle-canned it flat black. Then he puts one of those stick-on mailbox letters (his last initial) from the hardware store over the Volvo crest and calls it a day.
Feck. Even at 14 I knew that was a cheesy thing to do to a car.
