I just sold an early built Gran Coup with original paint. I bought it in 78. It was August or September built. I may have some information still in my files. It had a std silver argent grill with the chrome moldings. I still have one of the headlight doors as it was slightly deformed from a bent fender when I bought it. I changed the right fender and headlight door when I sold it last year. I did have another one years ago but it was flat black painted over the original argent rough textured silver. Is was altered to say the least. It had a 6” round steering wheel and a leopard print fuzzy headliner glued to the hardboard headliner. 😳
