MASTERING SURFACING IN RHINO Porsche 911 tutorial. Anyone bought it?

Hi. I am considering buying the tutorial https://www.food4rhino.com/en/resource/mastering-surfacing-rhino

Does anyone try out? I am a bit hesitant with the Ebook format…
Unfortunately, I could not find any good rhino video tutorial of cars in Rhino.

The only two I found that seem complete and detailed are the Audi TT and the Porsche one…both as Ebooks.

Thank you

Thank you
