Picked up my C3 1.6 eHDi Airdream (the nil tax version) on 1st March and took a trip to France. Travelling at 70 - 75mph most of the way on Motorways returned 72 mpg over 900 miles. Since my return I have done a further 100 miles of mainly short trips of 5 or 10 miles and the overall mpg has dropped to 61. The reading on the trip for the local driving alone shows as 51 mpg. While I have had the car I have accelerated normally and changed when I felt it was necessary rather than watching the change indicator. (44yrs driving experience both cars and bikes) I bought the Manual on Ebay from the guy who describes his customers as idiots and found the mechanical side loaded no problem but when I try to access the Electrical diagrams I get an error. No problem with my lights, they worked fine on my France trip especially on the A14 and A1 which was bad enough to undo a few fillings and leads me to my next point. The only fault I have found with my car is the rear suspension seem extremely soft and hitting minor potholes or heavy over-banding causes rear of the car to bounce towards the near-side. A change of shocks by the dealer has made no difference. Anyone else get the same feeling with the bumps ? Stobie
