I am trying to find a suitable sun shield to fix to the rear window of my Mk 6 Fiesta so my baby won't get the sun in his eyes. So far I've been unsuccessful as all the ones that can be bought (I've only tried looking in Halfords and Mothercare so far) are too large to fit the new design sloping windows on the rear of the car. Can any other fiesta owners tell me if they are having the same problem or whether they have found a sun visor that will fit the window adequately?
