I have a Series 2 manual and drove a Series 4 Auto.
I agree the 4.8 with the auto did go very well with the cars style and ground covering ability. It took the urgent edge off it and allowed a more pleasurable but still very quick pace to be achieved with less effort.
However given the sidepipes I am still sad enough to like bliping the throttle pedal on change down and using engine breaking due to the light weight.
I remain looking for a nice Series 4 Auto personally.
