First off, let me say that $3500 for a Trabant can be a fair price, but I would expect it at least to run. It does look like there are some descent spare parts though. http://www.ebay.com/itm/1966-Other-Makes-P60-/251786876235?&_trksid=p2056016.l4276
Yeah I was laughing at that last week. Bummer, I' on vacay in Florida and could pick it up on the way home. I'd give hima grand for it but not 3500
