Lamborghini Aventador 1/8-scale model is wrapped in gold and made out of carbon fiber, gold and platinum.

A couple of years ago, we featured a car that had a body made out of carbon fiber and an interior and wheels fashioned from gold and platinum and lined with diamonds. The price for that supercar, based on the Lamborghini Aventador, was a staggering $4.7 million. The hook: it was a 1/8-scale model! The man behind that model, Robert Gülpen, is at it again, and will offer for sale at an auction house another baby Aventador, but this one is wrapped in gold and will command a price of at least $7.5 million - making it the most-expensive model car in the world. Compare the model's price with that of the real thing - $397,500 - which means you could have 18 real Aventador coupes (!) for the price of the gold-wrapped model.

The car's details are even more impressive than the last model Gülpen produced, starting with the gold wrap. After baking the carbon-fiber model at a high temperature and under pressure, the body is wrapped in a gold sheet that's 1/1,000-mm thin. The resultant effect allows one to admire the gold hue, but the wrap is so thin that the carbon-fiber weave is plainly visible. The interior is lined with high-carat gemstones and the wheels are cast in gold and platinum, just like the last model. The doors open and close, the wheels turn and, while the engine looks like a smaller version of the V12 found in the full-size car, it does not function.

The materials used in the build are valued at $2.6 million, so what the buyer is paying for is the work behind putting the model together. The car will be mounted inside a bulletproof showcase with a Lamborghini logo made of gold, platinum and gemstones, among other goodies that are included for one well-heeled buyer.

Feel free to watch a video below of the original Robert Gülpen model from 2011, and be sure to check out the gallery of that car and this new gold one.
