The problem is that it is subjective.

I this event, 3353333 and 3333334 both cost 93 however the first gets you to PR44.4 and the second to PR 44.0. And while R$39,800 for the fifth body upgrade is not a lot for an experienced player, it could be for someone who has only been playing for a few weeks.

Another issue is that for some cars, the least expensive upgrade tree for a Limited-Time Series may leave you with a tree that will cost you more for series completion.

If we try to address every eventuality, then the articles become too long, and it may still end up being 100% accurate.

The compromise has been to have the RR3 Wiki:Upgrade Strategy Limited Time Series link on the main article page which directs the person to a page which works out the least expensive strategy for completion.
