Toyota's plan to build the GR Corolla at its Derbyshire plant in the UK has created an unexpected problem for British luxury carmakers — one that could push the price of a new Range Rover, Bentley, or Rolls-Royce higher in the United States. The connection isn't obvious until you look at the fine print of the US-UK trade deal signed earlier this year, which puts a threshold on total British automobile exports to America at 100,000 units annually across all manufacturers. Up until that cap, cars are subject to a 10% tariff.
