According to the court record, the group planned to rob the vehicle rental firm while working together with Batsirai Mhungu, who has previously appeared in court.
They were supposed to return the car on March 3 this year but did not do so.
The gang then created a fake registration book and sold the car to Cosmo Chirombo for US$8000.
The company discovered the offence and filed a report with the police who carried out investigations leading to the arrest of the gang.
The gang led to the recovery of the vehicle.
Austin and his gang stole nine other vehicles using the same modus operandi
