The new hilux will not be a patch on the old ones! Trust me i have worked with farmers for 20 years lol!
It all depends what you want it for if i am honest, if its going to be worked i would look at older izuzu as they are BOMB PROOF! They just will not die
Old Hilux also great, the Nivara is fine engine wise, its the clutches you have to watch, they do not last long
If you compare the chassis on older and newer 4X4's you can see they are just not meaty like they used to be. I know this is all to do with MPG but still something to consider.
If you do get an old Hilux, 3.0 only! Aside from the power, they are better on fuel (much better on the motorway) and are not prone to needing a new head.
