Holden has launched a new advertising campaign in a bid to keep as many customers as possible after its decision to end production in Australia by the end of 2017.
The campaign will run over the next two weeks and will feature on radio, television, outdoor advertising, in print and on digital platforms.
Executive director Philip Brook said it aims to ensure customers understand the Holden brand will remain in Australia.
"Over the next four years we have hundreds of thousands of world-class cars and engines to build locally and sell," he said in a statement on Friday.
"Beyond that time, we will be offering world-class cars sourced for Australia from General Motors' global network."
The campaign will involve Holden customers and employees along with sporting identities who the company says volunteered their time.
AAP reports it remains unclear what impact the decision will have on domestic sales. The first figures since the announcement will not be released until the new year.
