Checking out a Previa

[uHu]

Looking to buy a Toyota Previa as a family hauler. Found a 2004 D4D with all the bells and whistles, with 300k km (200k miles). What do I look for? What breaks on these?

I suppose at this mileage it's time to change all bearings in the engine, + seals and possibly valves. Injectors and turbo are changed.
