Thanks to Craig Saxon for the link, and Simon Schmeinta for posting these pics in Facebook: three Baurs in a private collection in Germany:
An E21 Baur in what appears to be Kashmir Metallic.
Our friend Jeroen Janssen informs us that: " It's Automuseum Nordsee. The TC2 is B46233, a 325iX."
Cabrio Targa by Baur
Simon did say:
"Heading north and discovered by accident the private North Sea Museum ..."
That is all we know about this collection, somewhere in the north of Germany.
Thank you, Craig and Simon!
Stay tuned.... if we learn more about it, we will post it here!
