You own a flying car! It's fabulous, flying above the traffic, avoiding the crowds, giving lifts to your friends. It can rise vertically, it's easy to drive and park, it runs efficiently on renewable energy sources so you're not polluting the atmosphere, and it has a large boot (or trunk, if you're a yankee).
Unfortunately, it's radio constantly plays the Chitty Chitty Bang Bang theme really loudly, and there's no way to turn it off, even when the engine isn't running.
I wish I could store my work trousers in my backpack without them getting creased so that I could change into shorts for the three-mile walk home during this unstereotipically glorious summer, and not have to worry about messy trousers the following day.
