Fascinating puzzle!!
The car fairly shouts "BMW" in looking at the grille itself and the general outline of the body.
However, the headlamps are separate, not built into the front mudguards/fenders a la the 327/328 series and the cooling louvers in the side of the motor hood are completely different from a normal BMW as well. Also, the wheel covers are different.
So, we seem to be looking at some sort of replica and may I ask if it is even something made in Germany?
