Continuity mistake: This film is based on the Rettendon Range Rover Murders in 1995, when some drug dealers were killed in a Range Rover, however in the film a new (1995-) Range Rover is used, I believe from footage at the time, a Range Rover Classic (1970-1995) was the car they were killed in.
Continuity mistake: The Bentley was set on fire at the beginning of the film at the car dealership, then it reappears at the end of the film outside Peter Chase's house.
