This one is hard, I know...
Here are 8 pictures of prototypes or styling models during their construction.
One point is for identifying who made them: not the customer (the carmaker) but the firm that made the prototype or the model in the picture.
An additional point is for who recognize each one of the car, but for some of them I don't know exactly the answer...
