@sophieschmieg @Pourroy @stux if cars aren't expensive enough, what about watches?

Starting with a Breguet Marie-Antoinette Grande Complication (30,000,000$), we can add a Chopard Carat and a Patek Philippe Supercomplication Henry Graves (25,000,000$ each), then a Jacob&Co Billionaire (18,000,000$)

There, with even 2 million left for a car.
