My friend DK I totally disagree with the above statement. In the period 95-98 an auto version of the 80 wasn't available in the UK. Luxury 4x4 buyers bought Range Rovers, Shoguns, etc, anything that was auto and the manual Cruiser was ignored as an option. This led the majority (not all) to be bought as tools of work and abused as such. It has to be remembered that I was in the market a\t that time and finding a good under 3 year old 80 Cruiser was as difficult as it is now. This is why petrol versions are usually in such better condition, the original owners used them as a luxury vehicles and looked after them as such.
Of course there are always exceptions to the rule and I know of 2 or 3 exceptional 80's which forum members own and pretty much treat as "classic".
When the 100 came out ( with auto box) buyers flocked back to them and the majority were dealer serviced for a good period of their life and are much less likely to have had "enthusiastic amateurs" trying to service themselves ( relative to their value) as a lot of the jobs on a 100 are a little bit more specialised.
There isn't much evidence if the electronics on a 100 being unreliable as well as the engine or drivetrain, no matter what is thrown at them, ask anyone who overlands one on here.
