And you take that as 100% en masse... I despair. If German manufacturers lose even 30% of sales to the UK they will be losing a huge part of their business. If you can't see that go to the same place as Jack Leach.
No-one. It will crash and burn. Germany have already said they are entering a recession, where will the find a few billion Euro's extra from? Unless of course they hilt taxes on their own. Generally that doesn't go down well.
Trying to be a pedant and patronise doesn't really work. People will not pay an extra tariff on a Golf or a Passat when these get introduced. They will buy cheaper cars from America, Japan, South Korea, etc.
