This state-of-the-art motorhome, known as The Volkner Mobil Performance Bus, comes complete with a fully-fledged kitchen, a high-end entertainment system, and even a secret storage space designed to tuck away a supercar! All of this luxury starts at a price tag of around £750,000 and rises to a fully-loaded £1.2million (not including the supercar) depending on the buyer's own choice of fixtures and fittings.
