I have just taken delivery of a new C5 LX estate with the 110 HDi engine last Wednesday 5th March from Dutton Forshaw, Preston. I also had it 'SuperChipped'. Only 5 miles on it delivery mileage with a full tank. I will let you know how I get on mpg wise when I fill it up. Performance already appears fantastic, trying to take it easy though. My father has also bought a C5 SX saloon from DFP which is being delivered on the 21st March. He is not having his 'chipped' so it will be interesting to see how his compares with mine on mpg. My father's neighbour has also bought a new C5 SX saloon from Dutton Forshaw and a good friend of mine has ordered a C5 LX saloon, all because of my recommendation! First impressions of my C5 estate very favourable. Well built and very comfortable considering it is 'only' an LX.
