Well we had a old mitsubishi L200 and pretty recently we upgraded to a Hilux 3.0l .These things have come a long way since the good old days, especially in the interior department .But they are also a bit more expensive to run compared to the older models but still they are good honest machines.
I'm not the biggest fan of the Navara and i think the current mitsubishi on offer is just plain old ugly .with the current market for vehicles in SL D-cabs are a very attractive options considering the other stuff on offer for that price b'cuz if u are going for a diesel jeep or something, minimum u'll end up buying something over 10years old if u r lucky.
But the ride is something u gotta look out for in cabs as u might have heard by now.
hope i've helped.
