Yesterday's comment on the other 400 from the Stainz museum resulted in the following update. Quite interesting and with a single owner. I now wonder who this person was and how much mileage the car has.
This example is a one owner car and is presented today in very original condition throughout even retaining its original Silver paint and original black leather interior.
Estimate: No Reserve
Registration Number: Austrian Registered
Chassis Number: F101 CL21701
