Hi
Just returned from my trip. It is very difficult now to follow the A30 as it has been swallowed up by other through roads, such as the A36 at Salisbury. Apart from that, it was closed at Chard with a detour through some very narrow lanes and farm yards. Went to Haynes Sparkford Museum on the way back, very good and interesting.
Very pleased with the A6's performance. 46.2mpg on the way there, coming back cruise control on set at 75 mph returned 49.5mpg. Probably cheaper than an electric car.
