If I am not mistaken, all first level gold upgrades cost 230 GC, while skipping all stage 6 races costs 180 GC and saves a lot of precious time. That said, stage 7 should be hell without gold upgrades, thus a potential toll of 350 GC for skipping all the races (7 x 50). That's 530 GC for a car that can be purchase for 440 GC with showcase discount (and even less with a better discount in the future). Upgrading seems to be the way to go, provided you don't have to skip too many races during stage 7. Either way, the whole challenge looks like a gold trap to me. It also feels like an unpleasant experiment that doesn't bode well for the challenges to come...
