Nothing at the moment as the car is only nearly 2 months old.
I like the car; it's very nice and comfy, and feels more solid than my last C3, but it's a bit gutless. My last C3 1.4HDi Diesel seem to have more power, and would fly up hills, whereas this car can struggle, and you need to change down a lot and give it a lot of revs.
Fuel consumption still ain't great at the moment; I am getting about 31mpg, which is a bit disappointing, but my friend who recommended this car to me, and also my past 2 Citroens, said that I must give the engine time to run in, and then I should see an improvement in fuel consumption.
The equipment spec is really good compared to my old C3 Desire.
I have March 2008 C3 1.4hdi and travel to and from Maidstone and London each day and return 64.1 MPG.
