Bulletproof Patriot Spawn
Ray's bulletproof Patriot is now available any time after completing the mission "Marked Man". The process is lore-friendly and authentic, copying the mechanic from Import/Export rewards. Just come to Ray's garage in Newport, pick up the GTAIII symbol and step outside: car will be delivered in a second.
Very useful to get your bulletproof Patriot back in case you lost it without breaking the lore of the game.
