I lucked out. I got into once of these recently...
Now for the important question. What bumper sticker would you put on it?
GRM stickers are an obvious choice. But for humor?
I was thinking an "Eat more possum" sticker but it doesn't quite have the hilarity factor. I did see a BMW with PORCPIN on the plate. I thought it referenced the old joke:
"What's the difference between a BWM and a porcupine? Porcupines have pricks on the outside." (rim shot!)
