Tbh can't see another car company moving into the factory,who'd want the extra cost of tariffs if it's a no deal brexit? Porsche have already said their cars go up in price by 10% to cover the tariff cost,and VW their owners have said it's a possibility of the other marques doing the same,so that's VW,Audi,skoda,seat,Bentley,Lamborghini and MAN trucks and vans.
Ford looking at closing Bridgend plant due to it being not very competitive and in the wrong place now at the end of a very long chain.
Nissan pulling new X trail car out of Sunderland.
BMW closing mini production for a month or so end of March while they look into supply chains and how brexit is going to affect that plant.
Finally Land Rover and their well publicised problems and also writing off 3.4 billion as losses,and looking at closing castle Bromwich plant anyway,doesn't leave a lot of other companies to step in and take over Swindon,but it's all project fear apparently
