Hi,
I'd ask if the electric windows work 100%.... they can be a real pain.
The transmission is probably the most Important thing on these.. make sure they can guarantee it's all 100% i.e. The TOD works as it should, shifting is smooth.
Rear view camera and screen are working as they should (those cameras have a nasty tendency to get full of water.. it's not a showstopper if it is u/s cos you can get cheapy ones from ebay...but a pain none the less)
Shocks... ask if any are showing signs of "weeping"
Has the cambelt been replaced?.... it's due at that mileage.
Make sure none of the glass is damaged (chips in the windscreen etc....It took me 6 months to get a replacement windscreen through autoglass!)
If you do import one... some of the parts are easy, Brake pads are the same as the Vauxhall frontera "B" series, the engine is the same as the Frontera v6/Isuzu trooper/Vauxhall Monterey.. so not too bad..air filter pack is the same as Frontera, some of the interior switch gear is the same. Exhaust system is Impossible to get but you can get one made up in stainless for less than the factory replacement..
Where in the u.k. are you buddy?
Lol! just noticed! Hertford Heath?.... not far away at all!
