It’s on ebay in Florida with a starting bid of $18k, BIN of $45k:

This isn’t a BMW, it’s actually an Italian designed, Spanish built Iso Isetta, who came up with the original design. Iso licensed the design to BMW, who also bought the tooling. The design was also licensed to VELAM, a French company, and Romi, a Brazilian one. Iso Isettas were built in Spain, Italy, and Belgium. Italian built Iso Isettas are some of the most desirable Isettas; the Romi and Velam versions are just as rare, but less valuable.
