Hi there! What is your current car? Would an FD 1.8L Civic's fuel consumption be enough improvement to warrant a change to this car? The 1.6L Altis is definitely a good choice though, if you are after fuel efficiency, especially with the manual variant.

For me, the bigger diesels are definitely more practical, especially if you carpool or haul a lot. The Pajero is real nice. Space isn't class leading and power is a bit lacking, but it's built like a tank and if in good condition, will still incur fuel expenses lesser than or at least similar to a gasoline compact sedan. It'll be best if you find a manual, but they're pretty rare.

Another worth considering would be the Ford Everest. You get a newer car as compared to the Pajero for the same budget. Besides the trademark name and good looks and a slightly less powerful engine, you get pretty much all the merits found in the Pajero. This is best enjoyed with the manual.
