Yes - you've worked it out lads. It is in fact the new SEAT Leon dual-purpose concept car.
While you are bombing down the M1 in the driving seat, what a waste of time it is having the wife sitting next to you, doing nothing except criticising your driving. Now she can be out in the fresh air doing the ironing on the dual-purpose rear spoiler. And so that she doesn't accidentally fall off, there is even a neat little place for her to tuck her feet into which doubles as the exhaust - that'll keep her toes warm!
