I thought I was be stuck on those events forever, too. ZR1 RM will be good for Like the Wind. You'll win the Toyota 88C, which will easily handle business in the GT All Stars event.
You should have a Countach from one of the earlier events that you can enter into the Historic Cup. It seems difficult but the AI seems too timid to pass a lot of times, especially on narrow Cote d Azure. Get in front and you will stay there, despite being disadvantaged.
You will win a NASCAR from the special events.
As for the FGT, well, I'm not too concerned about it at the moment. I've been buying cars and making tracks and just overall having a good time. Maybe later I will save up a few mil for it, but if you're getting annoyed, stop and do something fun.
