Shotts,
There's so much poop in your response I don't know where to begin. But let's just look at engine durability, since that's the only (relatively) objective part of your post:
1. I'm not talking about your three cruisers. I'm talking about ALL of the cruisers, AS A GENERAL RULE. For instance, my engine has the original HG and burns very little oil (I won't even get into the fact that you have a LEAK for crying out loud. Remember your posts about the leak that you have? How your son's LC has a leak? Seriously, what does that have to do with whether the LC "uses" oil or not? I will stipulate that an engine with a leaky seal with "use" more oil than one without.), but I'm not going to say that "80's have no HG problems, and they don't use any oil." I also have a dent on my rear quarter panel; I'm not going to say "80's have dents on their rear quarter panels," or "80's dent very easily."
2. There are a ton of I-6's well in excess of 200k still trouble-free. I would not be surprised if the number of trouble-free 200k+ 80's on the road outnumbered trouble-free 200k+ 100's by 10 or 20 to 1. However, that doesn't mean that 100's won't be trouble-free, just that I doubt the reliability will be as high.
3. HG issue: How many people on the board actually have a HG problem? Anyway, the numbers have been crunched, and it's not an epidemic.
4. Your saying that the 100's V8 is more reliable is totally absurd, if for no other reason than it is impossible to know at this point.
My son's '93 isn't leaking oil. It's T-case fluid.
My '97 isn't leaking oil either. The rear mail is sweating.
They both burn oil. The 100 burn zero.
My "engine life longevity" comments are based on what people have posted in the 100 forum. Additionally you can find added reliability facts from mags. The 100-series is the most trouble-free Cruiser overall to date. As yes....there's many more aged 80's than 100's. DUHHHH the 80's are much older.

They're both awesome trucks. Face it. No argument. It's just nice to not worry about head gaskets, overheating, creaking sun roofs, and the other stuff they eliminated on the later series. As for starter contacts? Who cares. $200 and it's fixed, plus you have an idea it's acting up.
