I now have to use a Mobility Scooter for 'walking' any distance. The one I have come apart easily and fits nicely into the luggage area of my Sportback. The actual seat goes on to the rear passenger seat. This rather restricts the space available for the cases when we go on holiday. Has anyone used Thule or Audi roof bars and a Thule roof box on an A3 Sportback and have any recommendation for the type of bars and box to consider.
