Highspeed Takedown Hypercar Chase event make sure you play it on easy for easier takedowns and faster grind. Takes around 20-30seconds to do solo and gives atleast 15.750 depending on bonuses.

Any car will do for the event i am using Ford GT with fame magnet set bonus to also get over 4k followers each time. Try to get as much money and follower bonuses on the parts as possbile to make it more effective.

Skip the first 2 cars and just gather speed for the next ones and you will onehit rest of the cars in the race.
