I'd stay away from the diesel + auto, absolute pigs to drive, and you either feel like you're standing still or that you're breaking it.
The V8s are much nicer, and on LPG not too expensive to run.
People have a lot of horror stories, but most problems are fairly straightforward if you know where to look.
Mine was very cheap, and it drives great. Sure it has its faults, but it also has 255k km on it, so I don't blame it too much. Very comfortable, and will surprise you off-road too!
