I'm missing "only" 7 cars, all of which can only be purchased with GC of course. You need to unlock those events which will allow you to earn fame so you can move on to the next level and get the GC rewards. See this discussion Best race to get money, specially what RR3 Michael P says. Everyone should try to unlock the Endurance_Kings, even spending GC. But until then you need to find those races which give you more fame.

I don't spend GC to finish series unless I've got plenty. I always try to have enough GC in case a good discounted car is put for sale. And defenitely, there is no need to spend real money.
