Very good.
"This means that in the absence of special content deals, the bulk of UK assembled cars would not qualify for tariff-free treatment under a typical free trade deal."
I presume you read that bit? Just another non story really isn't it. All it actually says is that any free trade deals need to take that in to account. We don't currently have a free trade deal, never mind a a typical one.
It also works in reverse, BMW may need to build a new engine factory pretty sharpish, so might Ford and PSA
Ford alone build over 1.5 million engines in the UK but they dont assemble any vehicles.
BMW make over quarter of a million, all exported.
But feel free to continue to spout hysterical nonsense, you still aren't going to get your referendum re-run.
