How very interesting, Gerd:.....................
As this is a "no lock" free for all at this point, I googled your latest, "Saratoga Twinax 4WD" and got three hits on a Bulgarian website that had exactly that terminology.
Unfortunately, the website is, or seems to be, no longer functional.
In any case, this is the only "cable" reference out of perhaps a hundred that I have tried that seems to be valid as a possibility for the name of this phantom vehicle.
I hope you have the correct answer.
