Just watch for timing chain rattle and the Dpf issues.
Chain was a recall if you complained about it and it met the criteria. Quite a large job.
Also the 160 or 180k major service requires the engine out to replace the vacuum pump blades, another massive job.
Prados can get away with removing one engine mount and tilting the engine over to gain access.
But, they seemed to be more reliable than the previous model, so you should be well sorted.
