According to the innovator, he has been collecting luxury car models from precious metals and stones over the past 12 years, for which he even founded RGE Robert Gulpen Engineering. He specified that this model can be made of "emirate gold", which will make it the only one in the world.
To create a prototype sports car on a scale of 1/1000 mm, 25 kg of gold and 700 diamonds worth 5 million dirhams (US $ 1.3 million) were used. The model will be included in the Guinness Book of Records three times: as the most expensive and most valuable in the world, having armored glass and the most expensive Lamborghini logo. It was first presented at the Frankfurt auto show in 2011.
