mattwnz: The mazda 6 is a nice vehicle, and I believe they have facelifted it quite recently , so has a lot of the new tech in it. Don't think they sell too many diesels though, because unless you are doing lots of km's the additional costs don't really add up. I sold my diesel recently for this very reason, and it did have quite a lot of torque up the Rimutukas.
People always make the accusation that Diesel vehicles cost extra, but when the difference of 80c per Litre in fuel cost is considered, as well as the greatly reduced registration costs for diesel vehicles and a similar servicing interval to petrol vehicles, I'm not sure that statement is valid any more.
When we first bought our Golf, the difference in fuel price was around 50c per litre and the RUCs $40 per 1000km. Now the difference in fuel price is 80c per litre and the RUCs $58 per 1000km. So the saving in fuel offsets the increase in RUCs by almost double.
An additional benefit which not many people know about is that owners of diesel vehicles can fill up at unattended diesel-only truck stops if they have the right type of fuel card. When I was last in Whangarei a couple of weeks back, the service stations around town were selling diesel @ $1.35 per Litre. At the truck stop it was $1.13 less the 12c per litre discount from our fuel card so the price per litre was just $1.01. So we have had extremely cheap motoring for the past 6 months or more, and a 55L tank full lasts for around 1000km on a long trip.
I'm not sure why the difference between petrol and diesel has ballooned out so far in recent months, because AFAIK it has never been this high during the past 10 years. Long may it continue!
