Johnny, I was in a similar position to you about a year back though my series completion rate was higher. When I was 14 or 15 gold cars short of full garage I calculated out how much gold was required to reach full garage then slowly worked towards that mainly through playing the game and occasional farming, only buying new cars if they were on sale but stopping short of the showcase discount, keeping that in reserve. Back then the gold requirements for each new update wasn't as high.

From early in the game I acquired each new car in updates. Once my gold reserve was above that required for full garage my focus changed to full series completion, again I calculated how much gold was required for that task. I reached full garage in April when the Bugatti GSV was in a LTS. What I noticed at that point is I could mostly keep up with the series completion requirements by acquiring all new cars and just farming Le Mans when there was a fame bonus day but to actually make some progress I needed to farm Le Mans 10 lappers more.

Now I only spend gold on upgrades required for winning new cars, or advancing series completion when those upgrades are on sale or if the car is in WTT. It will be a slow process for you, patience is required.
