Fantastic set along with the Chiron for wow factor opening the box. I got it for my wife for Christmas for her collection (never managed to find a GT3).
She finished the first book and the next two boxes of book 2 before she had a hearing implant op a couple of weeks ago.
She started building it yesterday as she no longer felt dizzy tilting her head. Turns out there was an incorrect piece in the next box and the required piece isn't used again in the the rest of the build . Now waiting for a replacement from Lego.
She has the worst luck with missing/incorrect pieces, must be every fourth Technic kit so far. Yet I have never seen anything missing from the Creator Expert or Star Wars sets between her and my son.
