The Securicar is a truck featured on Grand Theft Auto III, Grand Theft Auto: Vice City, Grand Theft Auto: San Andreas, Grand Theft Auto: Liberty City Stories, Grand Theft Auto: Vice City Stories, and Grand Theft Auto IV. It is essentially nothing more then an armoured truck, and is used to transport money; and on some missions to transport people. Unlike in real life, the trucks are not bulletproof, nor do the driver(s) carry guns. The truck is not generally recomended for anything other than regular street driving; as the uneven weight of the armor tends to flip the truck over even minor curves or hills. It can usually be found driving around the streets of all the games, but it is much harder to find an unlocked one in GTA Vice City (a Securicar spawns in front of a bank in GTA Vice City, but it's locked most of the time and it unlocks randomly) than any of the other games, however, the Securicar in Vice City is a lot harder to flip over than the versions in all other GTA III era games. In GTA IV, it can be blown up for cash, but by doing that, will cause the player to earn 2 stars. If the player does not want to get a wanted level, he can destroy the Securicar with a bomb from Patrick McReary's friendship bonus. The GTA IV Securicar is manufactured by Brute.
In GTA Vice City, GTA Liberty City Stories, and GTA Vice City Stories the Securicar has "Gruppe Sechs" on the side, a German language pun on the well known infamous European security company Group 4. However, this can be pronounced as "Group Sex", which is obviously how Rockstar Games intended it to sound, giving them a double whammy pun for this particular vehicle. In GTA IV, the name is changed to "Gruppe 6" but the vehicle still says "Gruppe Sechs" in much smaller print on various surfaces.
In GTA III, the Securicar is surprisingly fast, but it can easly tip over if turning even at moderate speeds. It is a rare vehicle (despite making its appearance as three Securicars during a bank robbery cutscene), and it is found in Staunton Island only. It does not have a logo, until GTA LCS, circa 1998.
In GTA IV, the Securicar makes its appearance once more, now with its newer and better design. its handling and acceleration has been greatly changed and now it will no longer tip over when turning through corners. it also has no problem dealing with gunshots and vehicle damage, but it is not explosion or fire proof so can be destroyed by a single grenade or RPG explosion. A tougher version of the Securicar is the FIB Enforcer which is all but invulnerable to gunshots.
