""I assume, on twistier roads, accelerating and decelerating, lugging up long and short and steep and not-so-steep hills, stopping and starting, slowing for roundabouts and speeding up again, getting stuck behind milk tankers on big hills, forever ramming it into third... bet that lot eats into your 35mpg somewhat! :-)""

I believe I have already covered that point, but just to add a little extra, on my last trip to Wales (Maidstone Kent to Anglesea), I was able to average approx 33 mpg, and on that trip, as you may or may not know, there is a considerable stretch of just such roads.

As for constantly banging it into gear, I don't know how much you abuse your car, but the impression you give isn't particularly good. Mine is an automatic and the cruise control gives pretty seamless changes and minimum throttle.

Now I know its a waste of time, arguing about caravans with a (rather less intelligent) Jeremy Clarkson clone, so if you've anything sensible to say on topic, I might respond.
