Great 4WD, Low K's, but still would not call it cheap by any standards.
Can use www.redbook.com.au as a guide, also you can see what people are advertising them all over Australia for, on the quicksearch at http://carsguide.news.com.au/news/ just go classified ads not the dealers.
I did a quick searck and they seem to be advertised from $27 K up to around what you are paying. #For that type of vehicle I would be looking at buying from the Public trustee Auctions where they clear the ex Gov and fleet cars. Most of the dealers buy there and then whac another 8 to 10 grand on them , why give them all your money. I bought my 4WD Hilux Xtracab diesel there, saved about 5k... #for Qld check catalogues for you area here http://www.pt.qld.gov.au/auctions/motor.htm
