Hi Dave,
Many thanks for your thoughts on the auto operation. An interesting one - particularly as autoboxes through evolution, design, sensors and other "refinements" enable a particularly economic outcome. On a regular journey of A303, b roads and towns, over 60 miles I achieve between 29 and 31 mpg.
On a run from Dorset to York, with stops etc - mainly main / motorways an amazing 36 mpg !! Given the car is 3.0 V6 petrol, i was delighted. My semi auto driving style is more auto than manual - fear not ! My original thoughts were that as you say it keeps all working parts, working.
Thank you again, I shall keep in touch if the dreaded " light display" - together with the notices.
Happy motoring with your "S" over the winter.
Kind regards
Dominic
