I have a Pajero Sport 2.5 TD, it's the same car. Just another name in another country.
I have had it since 2000, and it's great. Not the fastest car, but no towing problems with my 8 mter boat.
I do use the low gear when pulling out off the water.
Only thing is the 4 wheel drive.
It only locks the center diff. not the front and rear ones.
In the 5 years I have had it, I have only change the alternator (But it was quiet expensive)
Replacement parts on Mitsubishi are expensive, but it's a nice car.
Go fore it.
