In these events, all participants under the same regulations, and if you complete the event you will win rewards and experience. In Time Trials and Drift Trials, compete on the leader boards with players around the world.
Online Dealership
An [Online Dealership] has been added to the left center of the screen. In here you will find popular and rare used cars. You might just come across that one car you've always been looking for, that you haven't been able to find in the used car dealership.
