Commissioner Anna Rawlings said the conduct was an attempt to deny consumers basic protections afforded by the Consumer Guarantees Act (CGA).
"The basic protections offered by the CGA applied automatically to the motor vehicles on offer and this conduct was an attempt to deny consumers those basic protections. Important information contained within a CIN could have informed consumers' decisions to purchase and $1 Reserve also failed to provide this information," Rawlings said.
Cooper told the Commission he thought he could avoid his CGA obligations by claiming vehicles were a package of second-hand parts and regretted his failure to include CINs.
Judge Mary-Beth Sharp said, during sentencing, the 'second-hand parts' representations "departed substantially from the truth", and "there must be general deterrence for offending of this nature."
Rawlings said motor vehicle sales were a focus area for the Commission during 2018/19.
"We are receiving increased numbers of complaints in relation to the online purchase of vehicles and all motor vehicle dealers need to take careful note of their legal obligations to their customers and make sure that they are operating within the requirements of the law," Rawlings said.
