This is a classic car toy. I searched using images and it might be a Cadillac Eldorado? It's a pastel pink, square-shaped convertible, retro-pop and cute. I think it's called a pull-back car, right? You pull it back and let go, and it runs. It's a toy that a small child played with. I don't think there are any noticeable stains, but it was kept in a toy box, so there might be some scratches on the corners. I don't know anything about miniature cars, so I apologize if the car's name is wrong. A cool name came up even though it's cute, so there's a possibility it's wrong... Please be aware if you are at all concerned.
