More than 250 people have been made redundant with immediate affect after Drive Assist went into administration.
Zolfo Cooper has been appointed administrator of Drive Assist, plus Sol Rental subsidiary and its Millennium Motor Group subsidiary which trades as used car supermarket Nottingham Auto Park and retailed some of its defleeted vehicles.
Joint administrator Alastair Beveridge said the companies recently lost a major customer which resulted in cashflow pressures and administration.
"Regrettably, 259 employees have been made redundant with immediate effect. We will be working alongside all stakeholders to determine the most appropriate next steps for the benefit of all creditors," he said.
Drive Assist was established in 1992 and operated a fleet of around 17,500 vehicles, according to its website.
