Three men from a car dealership in Sydney’s north-west have been charged with allegedly issuing fraudulent pink slips on 22 cars.

The men issued pink slips on several cars despite serious defects including vehicles not having airbags or working brakes, it has been alleged.

It is alleged the men produced the fraudulent pink slip report between January and May this year.

Investigations began after police became aware of two heavily modified vehicles in Seven Hills as part of an unrelated investigation.

The cars were allegedly granted pink slips following safety inspections in April, despite the cars having their anti-lock braking systems removed and suspension that did not meet minimum safety standards.

Police subsequently charged three men aged 39, 40 and 42 years-old with knowingly producing false/misleading document state law and breaching condition of examiners authority.

The two older men were also charged with issue of false or misleading inspection reports.

All three were issued court attendance notices to appear before Parramatta Local Court today.
