cloners dont drive around looking for a car anymore, these days they go on car forums, its much quicker and easier and cheaper.
lets say i wanted to find a blue mk2 punto sporting plate in newcastle, how easy is it to go on a fiat forum and search for "sporting newcastle" until you find some sucker to clone. now compare that to driving round newcaslte all day until you see one. there is no choice, you go online. displaying your plate on public roads is far safer than displaying it on the net.
Me thinks ill change me sig now
