My suggestion for the next/future updates is to add a Challenge Series that has 3 endurance races.
Here is how it would work:
1.You can go in to the race with any car you own.That means your dyno,your setup and so on.
2.There will be no time limit,or to set a specific lap time.All you have to do is finish the race.
3.All classes are allowed.You can do the event with all classes,since each class you do will give rewards.For example,if you have done all the races with A class,you can do all of them again with a different class.B class,C class,D class,E class,SUV,Vintage and Muscle class.Once you have done one class,you can not repeat the same class again.
4.The rewards for completing all 3 races races will be 50000$,30 bodypoints,15 vinylpoints and 5 taskpoints.
5.There will be no RP requirement to do the races.
6.The 3 main maps for the endurance races would be:
1)Fierro Madness-70 laps
2)Ambassador Ridge-100 laps
3.Black Vincent-50 laps
Let me know if you like or dislike this idea.
