the way I see it, there are only three good options:

get R$ only upgrades the 25% and 50% completion reward for an extra 24 gold.

get R$ upgrades plus the level 2 and 3 drivetrain upgrades (costs 25x3) for all cars to get up to 75% completion reward for a total loss of only 31 gold but with slightly more upgraded cars.

get all the needed upgrades to get 100% and the sponsorship deal.

for the last option, if I understand the upgrades strategy page correctly:

972 gold cost in total to upgrade all 3 cars (with 50% off) to the needed PR.

without the discount, these upgrades would cost 1944.

in the end, you get all that upgrades for a total net of -672. if you have the gold, then this is definitely a good deal (65% upgrade discount in the end) because of the 300 gold you get from the sponsorship deal.

keep in mind the nearly 5 million R$ upgrades cost though.
