Marshall Motor Holdings has temporarily closed its dealerships across the UK, affecting 4,300 workers.
The decision followed advice from the government to slow down the spread of the Covid-19 coronavirus.
A statement from the company said: “Other than certain key roles, all of the group’s colleagues will be temporarily furloughed during this shutdown.
“The group’s key brand partners and banks have been consulted on this decision and remain extremely supportive.”
Marshall Motor Holdings said the temporary closure will “clearly have a material impact” on trading for the year to 31 December 2020.
The recommended payment of a final dividend for the 12 months to 31 December 2019 has been suspended.
