The Mafia Sentinel (also known as the Leone Sentinel) is a gang version of the Sentinel used by the Leone Family in Grand Theft Auto III and Grand Theft Auto: Liberty City Stories. It accelerates fast and has tight handling, and thus is ideal for street racing. In Grand Theft Auto III beta, the vehicle is named the Leone Sentinel.
The Mafia Sentinel is evidently a four-door sedan based on the games' renditions of the Sentinel, resembling a real-life mid-1990s BMW 5-series, but this car was closely resembling BMW M5. the Mafia Sentinel is also related to the sporty Sentinel XS variants in later games. It is essentially a tuned version of the Sentinel, with a bodykit, tinted windows, and blinds over the rear window. Its paintjob is always dark gray in GTA III and black in GTA Liberty City Stories, and cannot be resprayed into any other color in a Pay 'n' Spray. In the strategy guide for GTA III, pictures of a white Leone Sentinel can be seen. In the GTA III mission Give Me Liberty, there is a blue blown-up Mafia Sentinel from the GTA III beta.
Like any gang car, attempts to steal one with a Leone Family member inside will result in surrounding peers attacking the player.
Handling is slightly sharpened, whilst average speed is noticeably quicker over its stock counterpart. Its performance coupled with its four occupant capacity makes this an ideal car for bank jobs and attacks on rival gangs. The GTA Liberty City Stories rendition has a supercharged V8 engine and emits a same engine noise as the Sentinel XS
