Reached Tier 19 with 4363333 (PR 60) for approx. 136.8 GC at 20% off. Upgrading from Engine 4 to Engine 5 costs 48 Gold at 20% off to reach required PR 61 for final tier with the subsequent R$ upgrade, but I can complete series for 35 GC from here on and save 13 GC. Given that only PR 60 is needed to finish Spirit of Ferrari and net in the remaining 100% completion reward there of 28 GC, PR 61 is only needed to complete this time limited series. However, saving 13GC is only a short term gain (3 days worth of ads head-start); long-term a higher upgraded 500 GTO might help you out of it features in weekly time trial, eventually gets its own premium series, or is featured in a new series in a new update.
