Wow, some of those are really really slick looking! I used to borrow a neighbors Puch to tool around the neighborhood when I was 13 or so. I shared a paper route with a friend, and we both used a skateboard to deliver papers: a pile of papers on the front of the board weighted down with a brick, and just pushing ourselves from house to house. With the moped, we'd still stack them on the board, but would hold a rope and let the moped pull us along.
I could see myself buying one for picking up six packs from the corner store someday.
