Even if you move from D to 3 quickly, the car adjusts to the new ratio smoothly and quietly. The car has great stopping power, but suffers from more dive towards the end than say the Lexus LS430. With the suspension tweaked, handling is better now. It doesn't wallow about so much when taken quickly round bends. Yet, ride comfort is not any poorer for it.
Vibration is also undetectable.
Like its XJ cousins, the Sovereign is a friendly touring and golfing companion. Also, the car comes with a warranty and servicing package that's probably the most comprehensive in town. Running costs are therefore, relatively low, although its rather thirsty engine might offset this a bit. Last, but not least, the car looks great. It has a timeless design and exerts a presence few cars can rival.
