While the Land Cruiser is no doubt a very sturdy vehicle, but at the mileage you state it has done, it would demand some maintenance before it meets your expectations. The engine especially may need overhauling if not immediately then possibly in the very near future. That is going to cost you a bit while it will not get you a single riyal extra when you would like to sell off the vehicle.
On the other hand while you are getting a newer model of Pajero, you cannot match a Pajero to a Land Cruiser. Also, the spare parts of Pajero are costly compared to that of Land Cruiser. Possibly, that may be a reason why Mitsubishi vehicles don't have a good market.
Suggest, you save a bit and go for a newer model with lower mileage or alternatively go for a brand new car though a smaller one.
