One day, when I no longer have to ferry a child and all her attendant stuff around, and when I have a housekeeper to do all the shopping (I realise this may be quite some time in the future), I shall tie a Hermes scarf around my head, put on some huge sunglasses, sling my Birkin bag (gently) on the passenger seat and pootle off into the sunset in one of these.
The Hermes Smart Car, full of little Hermes accessories and available in a variety of colours to match all your Birkin bags.
