I am getting back into Asphalt 9 and have been grinding for about a week and a half (garage lvl 9 w/27 cars). I see I need some showroom cars for the career but I was wondering how people go about it? Racing 15 times just to get 2 blueprints for the i8 seems so excessive to me but I don’t see any other way to get that car and the other showrooms cars. Whats the best way to go about this? Should I start with the i8 or which showroom should I start with to go the farthest in career mode? Currently stuck at the start/middle of chapter 3 and just have been grinding to get blue prints. Thanks!
