Head to the location to meet up with Sitara’s contact. The paparazzi is located on the rooftop of the marked building so go behind the building to find the stack of objects you can use to reach the rooftop. Talk to the paparazzi and after exchanging some info with him, your objective will be updated.
Head to the marked location where the car is located. It is in a restricted area but it is moderately guarded so you can do your preferred approach to zap the guards or storm the place with guns blazing. The car is located inside a trailer truck parked inside the compound. Once clear, head inside and interact with the trailer to steal the car.
The police will be at your tail the second you leave the trailer truck. The supposed smart car also drives like a brick so you have to ease your finger on the throttle and use tight turns and alley pathways to escape the police. After losing your pursuers, drive the car back to Wrench's garage marked in the map to complete the mission.
