Hi ungli,
I own a '97 Prado TZ 3.0 diesel auto, and can tell you it is a very nice car. I owned a 2005 civic along with it, but sold it because i was using the Prado most of the time.
As far as price is concerned, I think you can get '96-'98 TZ Prado 3.0 diesel Auto in somewhere between 2.2-2.5 million.
If there are any questions, feel free to ask!
