Optional missions from your underbosses have five instances. You unlock one instance by default, and two instances per district assigned. So to get all optional mission instances for all your underbosses, you have to divide the 9 districts (the Bayou is free) equally among them. Equally dividing the districts also ensures that they'll remain loyal to you and won't rebel against you. Loyalty is also increased by completing these optional missions for them.


Talk to Burke to trigger a cutscene. He’ll have you find three orange Samson Richmond-Luxes. There will be several of them marked in the map. Head to any of the locations, smash the windows of the vehicles to steal them, then deliver them safe and sound to Burke’s place. After the third vehicle has been delivered to him, talk to him to complete the mission.


After giving a district to Burke, two instances of this optional mission will become available. For the second batch of cars you have to steal for him, you have to hunt down 3 Red De’ Leo Capulets. Just open your map and their locations will be revealed. These cars are usually located in police impounding locations so be prepared to either spend cash/markers to use the Police Dispatcher associate or get your hands dirty and take out the cops to steal the car. After delivering the third car, talk to Burke to complete this mission instance.


Talk to him again after the last instance to get another task. This time, you have to steal three Bulworth Aspens. Look for their locations in the map, steal the vehicles and deliver them to Burke’s compound. Talk to him again after stealing all three vehicles to complete this mission instance.
After assigning a district to Burke, the last couple of instances for this optional mission will become available. For this instance, you have to steal boats for Burke. You can find them along the river near Burke’s dock. Just find a speed boat nearby to get to these target boats quickly.


For the last instance, you have to steal three Samson Duke sportscars. As Burke suggested, these normally belong to Marcano’s men so be prepared for a “pushback”. Select the nearest Duke you can find and head there. There are usually 3-5 men guarding Dukes but they should be pushovers at this point of the game.

Steal all three and talk to Burke to complete his optional mission as well as the corresponding trophy.
