tuning
In GTA V you will find a lot of racing, especially street racing. So you’ll need a fast car, right? To get it, find any car and go to one of the tuning shops – Los Santos Customs.
Most tuning options are available for the sports car: you can change bumpers, add spoilers, and much, much more.
Such salons can also save you during your escape from the police. Just drive one of them (make sure there is no police car near you) and change the color of the car. The stars should disappear and you should be free to drive.
car wash
Driving on muddy or sandy roads or using only one car will pollute your vehicle. The only way to clean it is to visit a car wash.
Shines like a diamond.
For a certain price, your car will be completely cleaned.
Police parking
Did you buy an expensive car and it disappeared after completing some mission? Don’t worry, you will find it in the police parking lot. For the proper amount of money (usually $250) you will get it back.
Getting a stolen car from the police.
This happens to many cars, not just these. If you start to like a certain car and it disappears, it means that it is now in the police parking lot.
