I know a guy with a 2010 for ranger and it had to go back to ford to sort out rust issues ,
Tom it depends on your budget as well mate but the Hilux sounds good but they can be heavy on fuel . If i was to decide between the two i would go for the hilux just because it has less mileage ,
But if it has been used as a works motor it could have more wear and tear issues get it a good check over .
If you come across a truck that just been used like a car and never been off road or used for work it could be a better option also , check how it drives in 4wd as some folk have hardly ever used 4wd ,
I put mine in 4wd every 3 months so it gets a work out if you like to make sure everything is working as it should . MIKe
