Very different vehicles. the D1 and D2, althought they do look similar. I looked at both D1's and D2's, pre and post GEMS etc. I ended up with a 94 which is pre GEMS. All in all, it is simpler, distributor, last century electronics :-) and thus less trips to the dealership if you are inclinded to wrench a little. Also, codes thrown are read out on an LED under the passenger seat. Nice to be able to easily check codes.
The vehicle you are looking at seems like a good buy. These trucks must have had at a minimum, regular scheduled services. Don't go near one that has been neglected, but yours seems taken care of.
The culture of Disco's is great. Here, and discoweb and other resources are invaluable I have always found the advice I have needed. That said, my 94 is the least problematic vehicle I have ever owned, and most enjoyable to boot. But I religiously change fluids and jump under the truck every now and again to check things out. Stay on top of the maintenance and repair, and you will love these trucks.
They may be a tad under powered for trailering, but discos handle great with a trailer so that is a good thing to out weigh the under powered disadvantage. My 94 gets about 15+ mpg, this is driving windy, corrugated dirt roads for 10 miles everyday to town. Mine is completely stock, a lot of folks have heavy bumpers, racks, lifts etc, all which contribute to even crappier gas mileage.
I am super stoked on my disco, I love the thing, and I never cared much about cars/trucks before I bought it. If you go into disco ownership knowing you have to care for your truck, you'll be very happy. It is the people who buy a disco for the bling value, and expect it to just run forever, who are disappointed. That said, every vehicle needs care, but discos need unconditional llove
Your truck will love you in kind, but your wife may feel neglected.....
