Well, unless the website I just found is a complete spoof (which it could well be), it seems that this vehicle is called the Prêt , made by a company called Waspy (or is it just Wasp?) which specialises in wacky Minis, particularly as publicity vehicles.
It appears to have been commissioned by the sandwich shop chain Prêt à Manger, the design being based on a cardboard sandwich box which they had patented. Underneath is a 1997 1300-cc Mini. I'm not sure when it was made. According to DVLA in the UK, it was last licensed on the road in 2006, and has now been exported from the UK.
