Now I'm at 99% completion. The only things left I have to do are:
A-Spec
24h Le Mans
24h Nurburgring
Vettel Challenges
Gold GP/F
Gold Suzuka
Trophies:
1000 Cars in the Garage
Insane amount of money
A-Spec Level 40
All Golds
Platinum.
However since I'm a DS3 user, getting gold on the Vettel challenges is out of the question I guess. =(
