To be honest, I don't think there's anything out there in the UK pick up market that stands out at the minute. They all seem to have a few issues and plenty of reliability issues reported for all of them. Maybe the VW the best in that regard, but too pricey and too heavy on fuel (in permanent 4wd V6 form) for the mileage I do.
I do know that I can't live with my newer shape Navara though - too many design issues. Reliability-wise, there's been nowt wrong with it but I can't live with:
- Heater / aircon - either fridge or greenhouse - widely reported across forums that the AC is terrible.
- Electric windows - again, common issue. They're just so slow! Sounds such a trivial thing, but really is a pia!
- 4wd system - no centre diff so you can't drive it on anything grippy (even at slow speeds). Wind-up when doing 3 point turns on forest / gravel tracks is horrendous and it almost bounces on the spot!
- Seats - both me and the missus find them unbearably uncomfortable, to the point she hates us taking it on long journeys. I have a small hand-towel in the car I use rolled up behind my back to get comfortable!
- Headlights - mainbeam is too "dipped" and you can't see far enough ahead on country roads.
- Build quality overall is very poor. Classic example is the glovebox - designed to "pop out" to access the fusebox. Except it snaps when you try to remove it

Widely reported corrosion on the side steps as well - mine happened after about 6 months.
