its all media bs mate, they show rust buckets being defected, the public thinks they are only defecting cars which are unsafe, the public supports the defect scheme, police defect imports/modified vehicles, public thinks they were defected for being unsafe.
police arnt idiots, they know how to use the media, and the media know these sort of stories are well supported and are good for ratings and support, its a win win for both the police and the media, modified car owners are just the victim of stupid people who beleive media dribble.
im not saying they are only defecting imports, thats just stupid, but its not quite as good for image to show police defecting a clean stock car as it is defecting a POS which looks unroadworthy and dangerous, the reality of course we know is different, these clean, close to stock imports do get defected, and at ridiculous rates.
