There is a SUBARU IMPREZA WRC (1999) tutorial at https://www.blissdd.com/MikeThomsonWRX.htm

I'm currently working on it. (The first few pages, because I'm a total newbie with nurbs)

It doen't have the "click on this button, then drag the CV to the curve and attatch it with that button"-detail, but it's quite detailed.
