A replica model of a Lamborghini Aventador LP 700-4 in Dubai, UAE. This is the world's most expensive model car, made from carbon fibre and covered in a thin layer of pure gold. The 1:8 scale replica Lamborghini Aventador LP 700-4, designed by German engineer Robert Gülpen, is available to buy for £200,000. But amazingly this model – currently on display at the Lamborghini showroom in Dubai – is just a prototype for a solid gold model, which will go up for auction in 2014 with a price tag of £4.6 million.
