Well just don't do any races till tomorrow when the next seasonal comes out, hopefully you will have one of the cars needed for them and then you might just get your needed million.
i dont either, still done it with a fully tuned Chevy Corvette Stingray Convertible
And @ OP, yeah this happens so often, its pretty annoying, but its a big relief once you are able to get the car you've been looking for, this happened twice when i was trying to get the Mazda RX-8 LM Car before i finally got it the 3rd time
well I completed all the Seasonal ones i can so far ( i was saving up for the C9 that was in the OCD!)
So it looks like im waiting until tomorrow - i'll do which ever race is there and hope for the best that its still there... (with fingers and toes crossed)
