McLaren MP4/4 - i have found PR 106 (5333333) costs 680 GC -> LTS PR is 106,4 probably for 805 GC (5333343) minus 100 GC reward

Koenigsegg Agera R - FU has PR 89,3 for 825 GC -> LTS PR is 88,4 - one upgrade less is 605 GC (4443233) minus 130 GC reward

McLaren MP4-X - for career series PR 144 costs 1165 GC (7333442) -> for LTS PR 142,6 might be enough 830 GC (7333332 ) minus 100 GC reward

My guess on FXX K Evo 300-400 based on previous cars with similar purchase prices. See https://rr3.wikia.com/wiki/RR3_Wiki:Update_Gold_Requirements
