The model represents an endurance car of '70s. I don't see any sticker or symbol of car procuder (example: renault, ferrari, ecc), and so I think it's very hard this is a collectible. If you're so kind to read below the car and report all data, it'll be easier.
can you upload the bottom of the car I collected this car already yes it a rare car I just need to see the bottom of it then I can really tell you about it
I would check ebay and find similar and any comps you can find as well a find a niche marketplace where people interested in these types of collectibles gather
