Wants to buy a W123 300D still look for tips from you who know each other.

Hello and good evening, I’m interested in a 123er but it has a lip at the front is also the engine room should be called the mud flights (inside) are black and not in car color. It is a switch. Engine runs smoothly. Color is appearance bronze. From the outside it looks ok. E-window lift at the back and front. E-sliding roof. Year of construction should be 1976 but maybe not true, I find out another time. The 4 eyes face consists of each square and a round eye. On the other Se ite too. Somehow this lip doesn’t fit anywhere at the front. What should I consider? Would also like to have a 123 and hope for you. Thanks already. Sorry for the cryptic way of expression, I just wrote from memory.
