I think it has changed since the last post. I was able to unlock the next series, Euro Supercar by buying both the Atom3.5 AND the Caterham with R$, upgrading the Caterham to R$ max only and completing 28 trophy events. I didn't have to do 13.3.

12.2 was a complete pain in the a$$. I attempted it at least 50 times unserviced before the times came down to resonable levels and then only 3rd place.

You should be able to unlock the next series without any gold.
