Bike rack for car - 3 bikes (Arboretum)

Picked this up in the summer from another user as thought we might do a biking holiday, but that is now unlikely. We haven't used it - here is the original owner's listing from August :

"Halfords bike rack that can carry up to 3 bikes. Straps onto the back of a car. Been sitting in a garage for a while but last time it was used it was in good working order with all the straps."

Some of the foam pads are worn in places but I can't see it affecting use. One strap has disintegrated, but it's a different colour and width to the others and I'm fairly confident it was added by the owner for additional security. Instructions for use should be available online.
