In Redline: Origins, the reward for finishing within 3 days is the 375 F1. If you take longer than this but finish within 5 days, the reward is 15 Gold and R$100,000.

The 375 F1 costs R$3,600,000 to buy. Given the relative abundance of R$ and the scarcity of Gold, it may be worth it get the 15 Gold instead.
