That's not quite true. It seems we will pay a premium for certain German cars even tho quite inferior to our own.( Audis and Porsche over Jaguar, which to be fair are now Indoan) The Japanese will pay way over odds for old British sports cars...Yes but the reason you buy German product, is because you can buy it cheaper than tooling up to make it. Likewise the same British companies could at present buy their widgets from Korea, perhaps with a little bit of tarriff, but the lower wages there make it affordable...
We are all willing to pay over odds for what we perceive " quality". Bentley,Rolls,Ferrari have never sold on price.
That's the markets UK should chase post Brexit. We have an affinity towards supplying it and contrary to thoughts on here rest of world does agree.( McClaren case in point)
