This Gold-Plated Lamborghini Model Car Will Set You Back $7.5 Million

You won't be able to drive it at breakneck speeds, but this custom, multimillion dollar model car will surely turn heads anyway with its breathtaking price tag.

Said to be the most expensive model car in the world, the glitzy item -- a model of the Lamborghini Aventador LP-700-4 -- will go up for auction at a starting price of $7.5 million, according to CNBC. A prototype of the model car, which has yet to be created, is currently on display in Dubai.

To be crafted at a scale of 1:8, the model car will contain about $2.6 million worth of precious metals and gems once it's completed, according to the model's manufacturer RGE Robert Gulpen Engineering.

CNBC reports that the model car -- which will be about 15 times more expensive than an actual Lamborghini Aventador -- will be carved out of a 500 kilogram block of solid gold.

Last year, another gold-plated Lamborghini Aventador was put up for sale. It was, however, a full-sized car, complete with a 700 horsepower engine. Covered in gold foil, the one-of-a-kind Aventador AU79 came with a price-tag of $550,000.
