Here we have a vintage 80s Scaletrix set with two replacement model cars, which are quite rare. I have tested the transformer, track and speed controllers and they do work. The cars however do not work fully, as the electric motors run, but the wheels don’t turn. So, probably just needs some fettling with the gear set on the back axles. Other than that the cars aren’t in too bad a condition, although the glass is damaged on the Porsche model. I’m not sure if the set is complete, but it looks like most things are there (Not original cars though) There are 34 pieces of track. Please study photos closely for condition and if unsure ask me a question. Many thanks for looking.
