Finks motorcycle gang club enforcer Richard Michail, 38, and Matthew Ward, 34, were on April 16 sentenced in the County Court after they were found guilty of stealing the canary yellow Lamborghini Gallardo Superleggera in May 2010.
After arriving at Lorbek Prestige Cars, Michail approached director Srecko Lorbek and demanded they "go for a little walk''. Michail slammed Mr Lorbek's head into a car and demanded $50,000 before taking the vehicle.
He then threatened to rip Mr Lorbek's hands off when he tried to stop him, the court heard. Michail drove the car to the nearby Finks bikie gang clubhouse where it was later found by police.
Justice Mark Dean said the men, who were wearing Finks T-shirts, had used bikie links to intimidate staff.
"This was a brazen offence and your conduct must be denounced,'' Mr Justice Dean said.
"Persons carrying out their lawful business must be protected from acts of intimidation and violence.''
Michail was sentenced to 3 1/2 years' jail and must serve two years before he is eligible for parole. For his part, Ward was sentenced to three years' jail and will be eligible for parole after 18 months.
