Shortly thereafter, Federale Volksbeleggings Bpk, a subsidiary of Sanlam, acquired a majority shareholding in the company.

The business began to expand beyond South Africa into Botswana, Lesotho, Namibia and Swaziland and administered sub-licensees in Angola, Madagascar, Malawi, Mozambique, Zambia and Zimbabwe.

In March 2005, Barloworld Limited acquired the full ownership of Avis Southern Africa, hence the delisting from the Johannesburg Stock Exchange.
