A Table Mountain car guard said he thought a man "was joking" when he said they could have his brand-new black Audi R8.

The car guard, Desire Shima, told a radio-show host on Heart 104.9FM that the man ? known only as Rob ? spoke to him and another car guard for about three hours "about life" before handing the pair R10 000 from his wallet and telling them they could have his car.

"He took R10 000 from his wallet before he gave us the car. After that he said 'you can drive'," said Desire, who comes from the DRC.

According to Desire, the good Samaritan told the pair that he had everything he needed in his life, but wanted to start sharing with other people.

The Cape Argus reports that Rob is still the registered owner of the vehicle although he handed the guards car keys, registration papers and an invoice. It had been bought by the businessman in December and was fully paid for.

Despite being aware of the chain of events, police officers reportedly still stopped the pair, Fabrice Munganga-Mugala (25) and Desire Shima (25), on the suspicion of them driving a stolen vehicle. Both men are from the Democratic Republic of Congo, the Cape Argus reports.

The man has reportedly asked the car guards and the police not to identify him.

The car guards now plan to spread their good fortune by buying food and distributing it across the city using their new means of transport.

"The car doesn't belong to anyone, it belongs to the mountain.

"He gave it to us to show that if you can help others, you must give without wanting anything in return," Shima, a third-year Information Technology student, told the newspaper.

The duo have cut a slit in the bonnet for people to drop off messages or slip in donations. Around the slit are the words: "A better future for all." The engine is in the back of the car.

The duo felt it was necessary to create the slit so that they could spread the donor's message.
