We all tout great scooter deals when we find and/or take advantage of them. On the other side of the coin, what's the worst deal you've ever fallen for? Overpaid, hidden damage, something not working, false advertising, lemon of the century, seller ripped you off. etc. (Let's save how "not to get taken" or "I've never been taken because I take precautions blah blah blah" for another thread).
There's got to be some good stories out there.
