Mario's Rebel Drops

Head to the garage by the docks and start the mission by stepping on the quest marker. Mario will tell you to reach the marked location in your map. After reaching the location, open your commlink and set the waypoint to Manaea's garage as instructed. Just drive the scooter there to save it in your garage. From here on, most vehicles you'll drop off in the garages will be available in the rebel drop list.

Mario will also instruct you to get the signal beacon. Then, you have to open the Commlink and select the Rebel Drop option. Select Vehicles > Motorcycles > and the '69 Stria Sussuro as instructed. Now select your preferred two-handed weapons, dual-wield small arms, and special weapon (if you have any unlocked) then select the Request Drop button at the bottom. Press Triangle to receive the vehicle and weapons you requested. The mission will be complete.
