I have a 2002 harrier 3.0 4-wheel drive..bought it unregistered in end of 2004..car is in extremely good condition and has been very well taken care of..i have only used MOBIL1 synthetic engine oil throughout..
car has about 44,000km..so far excellent performance and reliability..rewarding drive and comfort..
however fuel consumption for the 3.0L engine is not too good..gives about 6km/litre with AC in city.
