Another question of course to follow on would be "Does my bum look big in this colour!"
I was in a local BMW dealer last year booking my Mini in for a service when I overheard some well dressed young woman tell a salesman that she would like to buy a secondhand 3 series. He asked her back would she like a diesel, petrol, automatic, etc, and she told him "it doesn't matter, I just want a black one" (I could see his eyes light up as he probably had an unsaleable large engined expensive to tax black one he could unload on her!)
