Hi Woflie, congrats !!
I did the same only a couple of weeks ago but I had the game for 3 years already and finally decided to go for all gold. The final S-licenses were finally doable after this long. Did you play the game for some time already or did you just started it 2 weeks ago? And did you have previous GT experience (GT1 and/or GT2)?
So again, congrats !
