All Pegasus and Special vehicles

Cycles because don't forget about them

Outfits (deadline suits add up yo)

Four offices + options

Nine floor office garage + options

Safehouse properties

Special Cargo warehouses

Vehicle Cargo warehouses

Biker clubhouse

Biker businesses

Kill yourself ($500)

Weapons, weapon mods (ie $47k Yusuf Amir engravings), topping off ammo
