Okay, I've never even ridden the MP3 but I have a question. I was in the grocery store and happened to hear one of our local scooter dealers chatting it up with a lady giving out free samples of salsa. He sells TNG and Kymco. I know who he is but he doesn't know me.
Anyway, I heard him say, "That Vespa three-wheeler is mostly hype, and harder to handle than a scooter." No bullshit, my wife and I both heard him say it.
So, is it hard to handle? My guess is that this particular dealer has "Vespa Envy." I may want to put an MP3 in my garage some day.
