I never look at the MPG as we all know it's not a true account, I do not really do enough driving to warrant a diesel which is why we opted for the petrol version.
UPDATE
I have been onto Fiat customer services now and they have opened up a case and should now be speaking to Vospers.
According to the guy at Vospers that I have spoken with they are telling me that I am unable to reject the car until they come back and say that there is an actual fault with the car itself. I do not accept that at all and if we do decide to go down that route then we will but I am trying to give them the benefit of getting this sorted otherwise this is really going to be our only option and then maybe look elsewhere or go for a different engine version
