Stumbled across a complete, good condition, 4 speed manual Chappy, and I know nothing more about them than what I've been able to cull from the interwebs over the last week. Regardless of value, I am likely going to buy it for the pure fun factor and to teach my youngest the way. Just want to make sure I don't let my heart get the best of my checkbook. Seat is worn and headlight mounts are bent a little from what appears to be getting a marker light snagged on something. I know it's not a moped, but you all seem to be a great resource on the topic. Can anyone help me with the value of this model?
