As long as you can watch ads to reduce the upgrade time you don't need to spend any to speed them up. Use strategy with Ads with watch some ads and still buy the required upgrades. e.g. buy all the level 1 upgrades, watch 2 ads x 7 to reduce the 12 hours to under 6, wait 6 hours and buy the level 2 and/or 3 upgrades, repeat with just 2 or 3 ads for each, or wait till tomorrow buy the level 3 and/or 4 upgrades.

Correction: Actually upgrades only need to be shortened for Engine, if you want to FU (not required for either car *). 12 hours + 18 hours can be completed within 3 days.

* See RR3 Wiki:Upgrades Strategy For 100% Completion, -1 Engine required for EC, although this may change when FM added it to Motorsports.
