correct, the entire vehicle is a poor copy of a Goggomobil T250.
There was one restored one in the USA that was near me and the owner was an absolute anorak about them.
For many years the story was that this was created by Polish engineers, but the reality was that they smuggled a Goggomobil in and then copied it.
He had an older friend, FRANK, from Poland that lived nearby who used to drive them when new in Poland and worked on that car in the USA.
They came over to my garage one day and I took them upstairs. There were piles of Goggomobil suspension parts on the floor from a project, but FRANK had never seen a Goggomobil and he exclaimed "MIKRUS!"
The body is different but all the running gear and the engine look exactly like their Goggo counterparts.
Unfortunately replacement parts are NOT interchangeable. Rather maddening when you swear it should all work but just doesn't fit.
