I'd say give the LN85 a shot.....not too sure re spare body parts, lights etc, but the mechanical spares are generally found. A friend had one for a while and he said that parts were generally ok to find. However this was about 2 years back he he....
On the other hand if you find a good specimen that hasn't been "brutalised' by the previous owner, you should be good to go.
The engine and drivetrain being what it is, are easy to fix, even if it means a temporary fix till you get the proper parts, drive back to civilisation etc.
I'm sure there are many more members here that can shed some light on the 85 more than I.
All the best anyway.
