As it's almost Easter and I'm feeling generous, I shall award the point to Targhediferro. I had this car under a very close but different name (made by Helmich, rather than Helmrich, with an 'r') but research into this Cord replica shows both names, with some English-language sources suggesting Helmrich, and German media (where I sourced this puzzle image) Helmich. The car was made around 1980.
