The other day, I pulled the car into the garage after a drive on a hot day. I happened to walk past the rear fender and I looked at the dealer decal on the trunk lid. It seemed distinctly crumpled, so I reached up, found a loose edge, and tugged lightly.
The decal came off intact -- and well worn! -- in my hand.
Apparently, the dealer no longer wanted to be associated with this car.
Of course, the dealer went out of business many years ago, so... :)
(I do need to get some cleaner out there and remove the remaining decal glue.)
