Several thousand sheets of gold leaf were needed to cover the Versailles-inspired special edition Mercedes S-class presented at the show, which opened to the public on Thursday.
Carlsson said it is only planning to produce 25 of the over-the-top luxury vehicles, each customized to fit the tastes of their buyers.
Ten of the Carlsson CS50 Versailles — named after the extravagant gold and mirror-decked palace on the outskirts of Paris — have already been reserved, said the company, which is targeting in particular ultra-rich buyers in Asia and the Middle East.
About half of the car's exterior is covered in pure gold, and the precious metal is also omnipresent inside the vehicle, covering the steering wheel, part of the dashboard and a range of knobs, buttons and details.
Carlsson says the gold inside the vehicle alone is worth €12,000 euros ($6,600).
And the luxury does not stop there.
The seats are fitted with Nappa leather and the floorboards covered with soft sheepskin carpeting.
It took some 200 man-hours to cover the car with gold leaf, using special squirrel hair brushes, before the delicate metal sheets were sealed with a clear coat to keep them in place, Carlsson said.
Priced at €359,000 ($498,000), the Carlsson CS50 Versailles on display in Geneva is among the priciest vehicles at this year's show.
it makes a far bigger dent in well-padded wallets than Ferrari's new version of its California T sports car and Lamborghini's new Huracan, both priced at around €200,000.
