The M&M Van

I drive past a construction site every day on the way to work, and almost every day, this M&M van is parked there. I finally remembered to snap a photo of it as I drove past (in my characteristic, gritty/urban/fuzzy-cell-phone-camera style).

Some of the logos have apparently been removed, so I don't think it's an official M&M van anymore. I'd love to know the story behind how a construction worker ended up with a van like this...
