http://cgi.ebay.com/ebaymotors/271156497335I'm not interested in this, but a friend is. If it was an Isetta I could look at it and tell what was missing or what to look out for.
I know next to nothing about Heinkels, never mind a 4-wheel version.
I'm not looking for what it is worth, but what may be wrong or missing given the information presented.
Neither of us are near where it is located so inspection is not really possible.
Someone gave up on this for whatever reason, or it got repossessed from a shop...or perhaps it was purchased from overseas crated like this intended for resale in the USA ?
That would sort of explain why it is already crated.
I have to assume some things are missing when it got packed up. Cars sold as a pile of parts are always missing things.
