Pajero is not as reliable as a Toyota and requires a expert Pajero mechanic to maintain it.
Pajero 2.8 diesel is not motorway friendly and unfortunately due to vehicle age, bad maintenance history, etc, the possibility of issues increases.
Pajero ride is better than a Surf but overall Toyotas are better.
Pajero petrol engines are better than diesels engines and have not heard of overheating complains.
