Such a stupid thing now, my brothers ex wife insisted on having one of the isofix car seats despite her refusing to learn to drive, and my brothers car not having the isofix parts required in the back seats. The quality difference between cheap and expensive strollers (we call em buggies here) is surely just weight and the way it looks, like most things. Tell me a mother doesn't want the lightest weight and most compact one possible? Babies aren't accessories women!
