It was designed by Italian coachbuilding company Carrozzeria Touring Superleggera in 2008 and is based on the Maserati Quattroporte sedan, utilising the same running gear and general proportions. The rear hatch and pillars are said to have added just 50kg in weight too, so the Bellagio has no problem sprinting from 0-100 in 5.2 seconds.
We're not entirely sure how many of these tailor-made Maseratis are out there - some sources say just 25. Either way, it's an extremely rare opportunity to see one of these things up for sale. It's priced at 165,000 euro (around $230,000).
