Hey Bazz I personally think you have nothing to worry about. I found this forum after I bought my 05 D22 and it did send me into panic mode somewhat with the stories of disintegrating turbos etc. but you have to remember you will read bad stories on forums because people need help/advice. What about the thousands of navs getting around just fine no ones going to post up out of the blue how there car is going great because they dont really have to.
From what I can tell 05 is good, built in Japan (apparently that is good) not too much modern technollogy ,think stick shift for 4wd instead of push button, not common rail, although the injectors and injection pump is a bit advanced for my liking. However there is still a lot of work you can do yourself on these things.
Have you downloaded the manual from this site. The more I read, learn about and work on mine the more comfortable i get with my choice.
