RARE 1980 Takara Porsche 935 Turbo Japan Transformers G1 Original Tomy Complete?

***1980 Takara Transformer***
Porsche 935 Turbo
I do not know much about this, but it appears to be complete. It is in the exact same condition that I bought it in, and I did not attempt to transform it into the transformer at all. One sticker is missing from the sheet but I think it was applied to the car already. For being 35 years old, it appears to be in very good condition. The box shows more wear than the car itself.
Condition: Please see the pictures with the zoom function, to get the overall condition.
