It means that you repeat something over and over again to get something of value in return to be able to buy stuff. In this specific case I had to repeat the races constantly for a long time until i could afford the car i was saving for.
oh. Thanks for helping with my case of stupidity. Yes, it's a grind, but you can get 40K from a drift race. More if you have coin bonuses. But yeah, the million dollar cars will take you forever and a day.
I recently got 5 dollars, should I spend it on Roblox, on money, or FH3, on the reveal treasure all thing (I have Ultimate edition) Ot I broke PCR, because the fastest in the game is like 270 something and my car can only get 269 or something like that
