This is silly, yes that is how they are shipped.
The Q3 is built in Spain, transferred by train for about 20 miles to Port (which is why the Martorell factory was built so close to Barcelona) then shipped to either Sheerness (or Grimsby and North Shields)) direct for the UK or if the ship is scheduled to pick up German built vehicles for the UK/USA it docks in Emden picks up the assignment then departs, the ships will then drop the UK bound stock and load USA bound vehicles (from Landrover/Jaguar mostly) and steam merrily onto your grand country.
Obviously the actual shipping routes do change according to demand and production output, but the auto industry do NOT waste money.
Makes more sense than US Q3's being built on exactly the same pline as EU versions but then trucked to Germany put back on a line to be "finished off" then trucked to Emden to be shipped to the USA on the same boat!
As you say...........nuf'said.
