Very different animals Don, though from a standing start I think the Bentley is just as fast. However, we didn't buy it for that but rather for long continental tours and it really replaced the Aero SuperSport for this that I sold earlier in the year. So far we've done just short of 5,000 miles since Sept and we are really delighted with the car and its performance.
No doubt that I miss the C63 and really enjoyed owning it too...
