With 500 miles gone the new S-Line Sportback is settling down, the suspension has become noticeably more compliant, it has moved from HARD to FIRM and is much easier to live with. My guess is that the dampers were a little, tight and have now loosened up a bit. Lady wife likes the ride so can't be that bad. A steady 75-80 on the M40 returns 47-48mpg so well impressed with that! One odd thing though, driving back in the rain tonight, wipers on single speed, exited the motorway, up the slip road and stopped at the lights - and so did the wipers. Weird, the next position up was the double speed setting, anyway the lights changed to Green and off I went - and wipers re-started, doing the same thing again at the next set of lights. Is this normal?
