Sir my recommendation would be first to know what exactly is your requirement. If it's just to have an SUV for nornall commute then get a newer model because the look and feel good but are of no good (for SUV purpose) . coming to your and other newbies biggest concern the trips to mechanics.
The main 3 reasons are onee people are have ideas about motorvehicles and secondly the go for low budget vehicles (as they assume it's cheap to build and properly maintaiin SUVs). Lastly the cut corners in parts and mechanics.
In my experience every vehicle demands to be properly maintained. Either. Get one from a person who has done that properly. Or spend initial time in good workshop.
Now the vehicle : pajeros are. Excellent ..... The problem with diesel versions like 4m40 on highway is because. Of the owners. They doont maintained it, and take it over 100km which the diesel versions are not good at it.
The petrol version 6g47 is amazing، the pickup too speed and torque lovely.
And I have one its for more than 1.9
