A BMW 318i with a sticker price of £19,995 (E29,992) was sold to an unnamed buyer at a London charity auction for £38,000.
So what was the added value? The signature of Nelson Mandela, inscribed on a trim panel above the glovebox.
The 3 series was one of 10 Democracy Cars built at BMW's plant near Pretoria, South Africa. Suppliers donated the parts and BMW workers donated their time to assemble the cars. In each case, former South African President Nelson Mandela signed the car to boost its value further.
BMW distributed the cars to its national sales operations in major global markets. The British auction, for example, benefited three UK charities including the Nelson Mandela Children's Fund.
