User blog:ChicagoCPA/List of Races and Cars

There are a lot of good lists on this wiki, but this is the one that I have been using to decide which cars to buy and which cars to skip (or buy at 20% discount and never upgrade).

I generally never buy the last upgrade for each category and have no problems winning races, which can save a good amount of gold coins.

Unless you are starting with a billion R$ and a billion gold coins, you will likely want to make completing the Porsche 24 Hour - Road to Le Mans 11 day series a top priority because once you own that Porsche 919 Hybrid, you have the key to the only race that will really earn you serious Racing$ for buying more cars and upgrades, namely the Endurance Kings Box 22 Mastare Prototype Championship, which is 10 laps around the Circuit des 24 Heures track and gives you R$ of 155,750, Clean Race of 77,000 and Fame of 28,400.

Which, if you use your Daily 100% bonus and hire the Manger and the Agent will net you, in 31 minutes, a total of: $700,000 and 56,800 Fame (which moves you up nearly 2 levels, so you get about 5 gold coins).
