The script adds a mileage counter for your own car. You need to go to one of the garages: in Ganton or in Doherty if you want to check it out, I also recommend leaving the car there at the end of the trip if you need to save the number you dialed. You can also take from these garages initially any car model standing there. The counter shows the distance traveled in (kilometers), in the metric version of the game. It is recommended to get out of your car only in garages, otherwise the script (value) will be reset. It is advisable to use a machine specially chosen for this purpose, so that you would not have to change it later. Temporary trips on another car do not affect the counter and do not knock it down.
