A regular at music festivals in America, the twenty-four foot long bus was built in 2007 by 36-year-old music lover Derek Wunder in California.

But with a baby on the way, Wunder says it’s time to sell his beloved creation. 'My bus creates a party literally every time you park it and music is playing,” Wunder is quoted as saying in UK paper the Daily Mail.

'This Rockbox is a larger than life conglomeration of the great ghetto blasters from the early 1980s.'

Capable of holding up to 50 people, the portable party bus boasts inbuilt DJ decks, its own on-board 10kW generator and rotating LED lighting.

It’s also got a massive 318 V8 engine, although sadly, it’s not road legal.
