Until then, Colin Parlett will temporarily occupy the post, which became vacant when Tim Englefield stepped down early in his term of office.
Englefield took over in 2006 from John Denton, who succeeded Parlett.
Zambakides, managing director of JZ Machtech, an independent Porsche specialist, is the IGA’s representative on the Right to Repair campaign.
He said he would happily take the post if the Right to Repair campaign progressed as expected and his company continued to do well.
“It’s time to reorganise the structure of the IGA and bring it into the modern world,” he said.
“We will focus on the new industry code, training and the Right to Repair campaign.”
He added: “I have a lot of ideas to put into the IGA.
“With a bit of luck and the right support from the RMIF, we might end up with a good IGA and one that people can rely on.”
Zambakides attributed the quick turnover of chairmen – Denton also left office early – to its voluntary status, which means that people who hold the position often have large independent garages and struggle to find sufficient time for another role.
