In 2005 he reputedly went on a R10m spending spree over a single weekend in SA, where he splashed out on properties, entertainment and buying cars that included a Bentley Arnage, a Bentley Continental R and a Lamborghini Murcielago.
Mangue has had several properties and cars confiscated over the years, and in 2017 was sentenced to a suspended three years in jail in France after he reportedly embezzled $175m from his country to buy luxury cars, real estate and other assets.
A previously seized collection of cars owned by Mangue – including a Ferrari Enzo, Porsche Carrera GT and two Bugatti Veyrons – was auctioned in 2013.
The latest 25 cars will go under the hammer at a Bonhams auction on September 29 at the Bonmont Golf & Country Club near Geneva. The cars are being sold on behalf of the Swiss government, with the proceeds to be donated to social programmes in Equatorial Guinea, an oil-rich but largely poverty-stricken former Spanish colony of about 1.2-million people.
Most of the cars have less than 1,000km their odometers. The Veneno Roadster, a super-rare Lamborghini of which only nine were built, has the lowest with just 320km on the clock.
Bonhams says the collection is estimated to realise in excess of €12m (R193.5m).
