After rigging the last batch of explosives, open the door to the garage then hop on the Bulworth Mohican. You have to escape through the dirt road or the old train tunnel. Either way, after getting to a safe distance, the rigged explosives will detonate automatically.
Lose Marcano’s Men
Now you have to drive your best to lose your pursuers. The Mohican is slow and bulky, making it really hard to control in chases so do your best in luring your pursuers to train tracks and offroads since they won’t be able to catch up with you. Just give attention to the minimap to plan your route away from your pursuers. Also, avoid committing too much crimes since having the police pursue you while driving this vehicle can be pretty challenging.
Take Enzo to Henrietta’s Hotel
After losing your pursuers, drive Enzo to Henrietta’s Hotel in the southern outskirts of Delfray Hollow. Drop him off to complete the mission.
