Missed that

[Hazey-n-Marc]

Do you have another one ready, or should i go?

I have my lovely one.
It remembers me some kind of fish or even an alligator head

[Sciu]

on first instinct : prototype of NSU Ro80?

[Hazey-n-Marc]

I can see what you mean, just checked and can find no links between the two!
Not a NSU.

[pietschokkenbroek]

mm looking at the picture..... I think it's build between 1850 and 1990 

[jaybee]

Could it be a four door Porsche prototype?

[Hazey-n-Marc]

Not a Porsche. Think you are right with the build date Piet  
It is a prototype, it was designed as a replacement for another car, but never went into production.

[jaybee]

Peugeot 504?

[Hazey-n-Marc]

Not French.

Clues available.
