-Bobcat (Bulletproof, Fireproof, Explosionproof)

Staunton Warehouse Garage:

-Stretch (Allproof, immune to all damage, Unique Color Black)

-Barracks OL (Bulletproof)

Shoreside Vale Garage:

-Patriot (Bulletproof)

There are also a Diablos Stallion and the Stinger (My favourite cars) that I wanted to convert into Allproof vehicles with the AP conversion trickbut I didn't do that since I don't enjoy this game very much and I am also unsure if that trick got patched out or not in the Definitive Edition.

If you want to grab the Achievement for 100% completion then just finish the final mission.

Installation:

Go to your "Documents" folder and locate the "Rockstar Games" folder. Within it open the "GTA III Defintive Edition Folder", then open "Profiles", then open the "Rockstar ID Folder" and place the save files in there.
