I didn't read every single post so forgive me if I said something that has already been said. Here's my opinion. I'm driving a 2001 Ranger myself.

1. Ford Ranger (older model) - Tends to have problems with the clutch. Got mine changed at about 80'000k's. I'm having problems with the clutch pump valve too. My mechanic suspects that it's too near to the engine thus being too hot. Rear axel tends to give way prematurely with heavy loads. Not sure if they have addressed these issues in the new Ranger.

2. Hilux Vigo - More spacious interior. Lacking an intercooler but better fuel economy. Can't fit a bull bar and go off-road due to the air bags. Don't like the clutch pedal. Too darn high.

3. Frontier - Lacking of a limited slip differential. That's why it's cheaper.

4. Defender - Good non-rust aluminium body but engine is pretty expensive to maintain. Most avid offroaders with a Defenders just keep the body and change the engine + gearbox.

Nothing about range rovers, pajeros, prados as they are in a different class.
