I know they are considered a bit naff, But, due to an old neck injury reversing sensors are a godsend to me. My Avant Sport is not fitted with any What I would like to know, do the sensors fit a specific bumper with clips on the back? Im assuming the avant bumpers are the same, just the lower section is different?? If I need a reversing sensor bumper, has anybody got one for the Avant, silver would be even better. ?????
