I saw one once. Too many times has Rover or BL or whatever been bailed out. It's simply not viable. If it was a modern, efficient plant like Nissan in Sunderland or Honda in Swindon then it would be. However, the unions have and continue to wield too much power, so that level of efficiency can't be achieved because it would mean job cuts, and the Longbridge plant is old and not set up for this, unlike the much newer plants at sunderland and swindon.
