Hi there
when u have purchased it , now install it.
I tell u One thing.
Install it and Enjoy it Have fun but when u approach roundabouts, or any other place where there is a police officer, remove ur leg from the accelerator pedal. so that the car doesn't make a loud noise.
But i was caught by a police officer in his regular car in a residential area and he didn't fine me anything, just told me to remove that as soon as possible.

Good Luck in this hide & seek game
