Actually, I try to make the Pinin. It is less easy because I don't have a good blueprint.
For help, I will try to explain how I proceed and expect help some people (@GTAman18 for example

).
First of all, you need a project and the motivation.
Resize the blueprint of the car in order to have about 2000 pixels length. (CTRL W with paint)
On the side view, record in an excel spreadsheet the coordinates with paint: first value = z, second value = y. Record the number of the point.
On the front view, slice the car in the middle, 0 is the middle (x coordinates) and record it in accordance with the side view. Note that the value shall be negative in my example.
At the end, you will have something like the attached pictures.
