The ultimate pre-war small horsepower Rolls-Royce, the Wraith was more refined than the 25/30. It had an improved engine with a crossflow cylinder head and independent front suspension, similar to the larger Phantom III. However production was curtailed by the intervention of World War 2 and it therefore remains a comparatively rare car.
