Rewards: 77 Gold, R$77,000
Location: SEASON 1
Unlocks from: Own Any Car in the Series
Maximum Required PR: 93.4

There are 51 events - 48 Trophy + 3 TT – with each car having a specific TT and 2-event showcase.  Any single car, suitably upgraded, can reach at least 75%, but only the Porsche will be able to be upgraded enough to open the last 2 cup races (PR 91.4/93.4) to complete the series.

Progress Rewards split:
25% - 9GC and R$9,000      [PR 72.9 using Brabham, PR 76.3 otherwise]
50% - 15GC and R$15,000   [PR 78.6 using Brabham or Bentley, PR 82.0 for Porsche]
75% - 21GC and R$21,000   [PR 84.4]
100% - 32GC and R$32,000  

(As far as I know we don’t yet have upgrade costs for the Porsche)
