Finding a job is not easy and it would be better if you have some skills since that would assure you that you would land a job. In your case, you are a thief and that is your skill. You have done some car nap in the past, so now, an illegal businessman hires you to steal cars for him. This is not a safe job as you could get busted, but at least, you don't need to find some buyer. You won't be earning much per car, but you would earn more since you can concentrate of what you do best.
The idea here is to steal a car and park it somewhere. You need to get close to the car to steal it. Some cars would have some sort of lock, but most cars won't have it. If that is the case, you would need to unlock the car to be able to drive it to a safe zone. If you can't disable the locking mechanism then it would trigger an alarm and you would get yourself caught, which immediately ends the game. The game gets more exciting and complicated as you make some progress.
Are you ready to steal some cars?
