Hmmmm!!
I am rather embarrassed here and I apologize.
I took as "the absolute truth" the information I got on this car from a source I have used for years that has almost always been 100% correct. I did not pay too much attention to the louvers in the motor hood on the artist rendering and I should have.
As Hansa and Borgward civilian vehicles are not part of my normal research outside of a general interest in coach built cars of the 1930's, I was not up to speed on the different models and I apologize for that.
In any case, the short lived Hansa 2000 certainly is different with respect to the hood louvers as is the 2300.
I have a new source now and it states that only 200 Hansa 3500 cars were made 1936-1939 and most seem to be 4 door limousine type sedans with full sun-roof.
The 2000 was apparently made in 1938 as a Hansa and in 1939 as a Borgward after the takeover. 2,000 examples.
The 2300 was the successor to the 2000 and was built in 1,000 examples from 1939-1942.
Below are some example photos.
