I actually live in New Zealand, city driving is much more mild than you would have in the states, I only live in a small town and the car is driven warmed up, not little start stop trips. As far as I know the engine in NZ specced cars does not have any form of EGR system. PCV valve has been replaced, air filter is new, plugs, dissy cap and rotor button are new, tyres are as hard as I would want them to be. Actual km/l has been done and is a consistent 7km/l, which is crap. There are V8's over here that do better than that. The car has done 210,000km but runs perfect, apart from the gas mileage, and uses no oil.
