(adsbygoogle = window.adsbygoogle || []).push({}); Worked this out with some friends while boosting "The Parking Garage".

1). Start a mission and get into in a friends car.
2). Stay in the car until the mission is over and you get a copy when the round is over.
3). Feel free to either sell his car, or park it in your garage.

All upgraded and custom parts stay with the cars as well.
I never payed a penny for my ones

So far I have cloned for myself.
