Rangie -

Drinks more than I do
Gearbox probs
Transfer box probs
Front hub probs
Steering stabiliser probs
Easy to invert
Chassis rust
Parts of bodypanels too
Tyre costs horrifying

But a huge grin factor! I was very sad not to be able to take up an offer of a 110V8 at one stage in my life... but 10mpg with the wardo on the back was going to kill me.
