nail in the coffin for british car manufacturing?

give how many cars are now actually made in the uk, this would be a prefect opportunity for France, German, Italy etc to load the dice, lets face it the brits are never going to dump there german brands, so imposing a nice fat import duty on british made cars would be a sensible move, honda, toyota, landrover, nissan, mini etc would be stupid not be looking into alternative euro based sites
