The inspiration for it was a generic CAFE downsized American sedans. I unconditionally give you permission to use this model at your discretion, modify it or implement it into a digital product. Use the model as you see fit and have a nice day. You can also choose authentic period colors from the table that I have compiled for models of this type - take them with a color picker directly from the picture: https://www.behance.net/gallery/217757079/Muscle-cars-color-matching-Game-models
