Thanks again guys!
As i said the client has pointed several errors and i am trying hard to correct them. Using blueprints from SMC and a lot of pictures. I will play with the colors, maybe even try the top-body 2tone.
It turned out a 66 2-door and a 61 4-door must be modeled, so i saved the 8-louvered wheels and black-centered small hubcaps to use on the 66 model.
For now let's proceed on the 4-door. I want to get the shape fixed before cutting the seams.
