Pathfinder 3.0L V6 Engine

Hey, Im looking to buy a older Pathfinder, I'm currently looking at a 1993 Pathfinder with the 3.0L V6, It has 300,000km on it, I was looking for some insight on the durability of that engine. It runs like a charm and drives like one too, any thing I should be concerned about, Pros? Cons?


Thanks
