As soon as someone from a car company says Brexit is a bad idea the Brexiteers jump all over them with their 'project fear'. According to them their is a 'bright new world' out there for trade. Obviously, motor manufacturers 'don't see it, don't get it etc'. Incredible, they are going to 'make a packet' but are against this by warning that Brexit will be disastrous for car manufacturers. As far as world trade goes for UK cars the strategy will be made in Germany, France, India and Japan not in London.
Car manufacturers have worked out about supply chains, WTO tariffs on their goods sold abroad until there are trade deals. They will have factored them in including the added costs to transporting more goods around the world. How many UK Nissan's sold in Australia are made in Sunderland? Same how many in Brazil, Africa? We are told that the Commonwealth will take up the slack. How many in Africa, India, Asia can afford a UK made car? Courtesy of 3 men in a pub. A very good watch is 3 men in a pub Brexit part 1.
