Yep, I have started and found that, Mclaren P1 can be maxed upto PR 78 with only R$ upgrades, so stage 20 is unlocked with it. But to unlock MOTORFIESTA series (stage 22), we need to upgrade it with GC. If any of the RSR 2013 or RSR 2014 is bought, then we are done with it and will wnlock the next as their showcase have 2 races each.

If 100% completion is kept in mind, then its cheaper to upgrade P1 and I would say its final option if any of the RSR isn't bought.

And dont buy them with 20% discount, as with the difference of GC extra paid 40%(on sale)-20%(showcase discount), you can upgrade the car and use it in another series as well.

All the best..!!
