Well the current tariff on finished vehicles from the US to the EU is 10%...

And you said,
But now you're changing your tune...
Yes and without a tarrif the EU manufactures are just about comletative with those imports from outside the eu.
Given the uk could potentially negotiate a lower tarrif for those vehicales post exit (or keep them the same) adding a tarrif to the eu vehicles would bump them above thier competitors.
How am i chsnging my tune?
Im saying theexact same thing inwas then the eu countries wouldnt want tarrifs that make thier products uncometative in the uk market.
Thats shy we have tarrifs for places outside the eu to try and offset the low cost products they are able to produce
