hi and welcome, im in Brisbane/Gold Coast and have a 3.0d 2005 sport

and if your looking at 4.4,s and only want to do a few km per year its probably ok but as stated if you think you will be doing 20 / 30,000 km per year get a diesel, i average a little over 30 mpg or around 8 to 9 litres per hundred, and thats probably better than many 4 cylinder cars, plus the redgo is cheaper
