Nissan or Jackaroo diesels

You need to check the service history, as it can make a huge difference to longevity of a diesel. My previous 4WD was a Nissan MQ with SD33 engine - clocked up 1.2 million km before it died. Had regular servicing and that's it. So high km is not as bad as poor service history IMHO.
My mecahnic says that with proper care, a diesel will get 4-500,000 km before rebuild. TD can last just as long, but servicing even more important, due to increased stresses in the engine. Non-turbo engines with add-on turbo are hard to assess. Depends on the design of the engine to cope with the increased stresses.
In general a diesel with 240K on the clock will still have a few good years left in it. The Nissan diesel will outlast the one in the Jackaroo, but it drinks more. Have fun looking.
Just my opinions.

don't forget, it's not just the motor thats done the K's, its rest of the mechanical components as well, diffs, gearbox etc...choose carefully

Why not include Pajero and Discovery. Pajero probably has the best diesel engine for longevity and reliability of the lot, and there are some good Discos going around at pretty good prices. There was one model Disco that blew head gaskets, but other than that they are not a bad vehicle.

Thanks guys. As usual, all good information. That's what I like about this forum. I have a preference for Jacks as I have one now and I am very pleased with it. It is just getting a little old, but still going strong - at the moment. My second preference is Nissan only because of friends and their experiences with them. Pajeros are my third preference, but there are not many diesels for sale. I don't want to go into the Toyota argument, as what car you like is personal preference. I'll keep looking and reading. Thanks for the comments.
