What I do is farm, when I want to spend the time. I have a seven lap Le Mans open, not the 10 lap ones and it takes 27-28 minutes. I collect as much gold as I can. I have about 5 million R$. Then, as the events come up, I calculate how much they will cost. If it seems too much to spend, I just to the R$ upgrades and try to reap as much gold from the event as I can, then I let the car go. If it is a car I want, normally I try to win the best rated car in the upgrade, at the least, then I do the needed gold upgrades to win it. Then, if the career series has a good farming race, I might upgrade the car to get to that race.

Calculating what it will cost to win is a bit involved. It depends on knowing the PR required to win, and the cost to obtain that PR. Through a combination of several pages on this wikia, the information can be had. Additionally, it requires copying data into a spreadsheet, sorting it on upgrade level, then R$, the GC costs and doing a cumulative sum on PR, R$ and GC. I do the calculation for each event, shortly before it starts. The result helps me decide if I want the car or not, based on my GC reserves.

In short, the answer is, it depends on how much gold you want to farm.
