ROOF RACK - universal fitting (for any hire car)

[tonybee]

there's a couple for sale in the A.A Auction house next to Longo's

[seathomas]

I need a roof rack to fit rental cars (without roof rails) - anyone have one for sale; or does anyone know where I can get one in the region (I have tried Avila in Vera, and a few other car accessories shops)?

Thank you.
