Yea, it has to be a certified install if you want someone to insure it...
I had one too - 4.0 Limited, bought it with 3 months T&T for a whopping 350 quid. Real nice machine to barge along in

Made a good noise and had a fair turn of pace as well, the straight six is a nice motor with a good heft. That was with a new towball, towbar, load tray and dog guard
You really don't get much more for the money.......Everything worked spot on, drove perfectly and used no fluids.
No wear to the driver's leather either which was remarkable!
Pretty bulletproof as well by all accounts and easy to eek a few extra MPG out of them (better electric fans, ignition, filter etc). Mine wasn't actually that unreasonable on fuel either, was mostly just sitting on cruise on the motorway floating along.
Decent spec as always - central locking, air con, cruise, electric seats, selectable part/full time 4WD, electric windows, mirrors, cup holders, power steering, ABS and so on.
Comfortable too!
Look for rust under the rear seats, where all the crud collects on the chassis. Other than that, just the usual. The engines are nigh on indestructible.
4.0's the one to have, regardless
They're cheap because people think they cost a fortune to maintain, are impossible to get parts for and suffer absolutely horrendous economy. None of which are true.
