I bought mine new in March & have put 13,500k's on it mostly highway use going from Forster to Sydney and back.
The economy is outstanding as it uses half a tank each way which is roughly 350klm.
I reckon it would average between 4.5 to 5.0L/100klm
The only issue I have is there is something loose in the dash & when you corner you can hear something rolling from one side of the dash to the other but other than that its all good.
Has anyone done any mods to there's in regards to exhaust or know of anyone who has?
I have the same thing in the dash something roles or knocks when turning... I had an issue with my exhaust something was wrong with it. Ford replaced the exhaust under warranty no worries. It was making a loud sawing rattling sound when the revs would come down. Car has 12,000k on it.
