The assembly did not cause any problems at all. The chassis is movable, the torsion bars are working, but the track is vinyl, I secured it with superglue. I made a ZIP Zimmerit from putty. In the end, I just applied a thin layer of putty and made "notches" on it with the back of a modeling knife. I tried to make a damaged Zimmerit.
I added a cable and glass to the driver. I made a winch cable from a headphone wire.
There is no connection to a specific car. I tried to make something from the "late production" ones. (I understand that the series, to put it mildly, did not work out)
