Jut finished this seasonal. I was in the "step in the right direction" camp. Prize car SP1. Huh? Really? I have 3, all 0/0/0. I bought one way back when, won one someplace, and one popped on a ticket. Now I have 4. I would have preferred a different prize car.
On a side note, finished Green Hell clean and on the first try. Took me until today to finish Tokyo. If you lose the draft there, it's a long race. You're actually better off not passing in some cases to set up the draft for the next section. The AI has some special tires for the right bend after the first hairpin. I could not, even drifting the car, keep up with them there. I also had problems in the long sweeper 2 turns from the straight. No matter how I feathered the throttle, they still had a faster line through there. Didn't catch the rabbits (There were 2 on this one for me) until lap 9. Used the draft to pass the #2 car just before the start/finish to start lap 10, which propelled me right on top of car #1 in turn 1. I let him do his thing until the chicane before the short straight. Caught and passed him there and just hung on to win.
