In my quest for a 4dr pajero/montero I've been doing more research.
I did a cost benefit analysis between a higher mileage 3.5 DOHC and our current diesel with major maintenance for another couple hundred thousand kms, and the diesel ended up being cheaper after only the first year, mainly because of the inferior mileage of the 3.5. (much worse, at 16-19 l/100kms vs 11-14l/100kms).
I took into account setting both vehicles to a reliable base line of basic maintenance, oil, fluids, belts etc. assuming 25000kms of yearly use.
I also included the timing belt and valve stem seals job on the DOHC that most need immediately upon purchase ($$), and an inevitable head and gasket job for the diesel ($$$) with all hoses/belts/fluids etc for the 2.8L around 200k to 250k.
What I found,
is that in less than a year, the gas model will end up costing up to 1500 more a year, just in fuel (at Calgary gas prices, not lower-mainland)
Also, after doing more research on the OZ forum. If you add bigger tires, armor, roof racks etc, the fuel economy drops to as low as 21+L/100kms.
I have to admit, I've been eager to switch to a gas model, and even testdrove one yesterday before hearing of 450km per 75-80L of fuel, and had $$$ flashing in my eyes! Im really happy I took time to do the spreadsheet!
