well, comparing the 80 and the 100 here goes:
- on the road, it is absolutely clearly unambiguously a sheer absolute fact -IMHO- that the 100 smokes the 80 in all respects. The 100 is soooo much better it's not funny! I can guarantee that the guys saying otherwise have either a) never driven a 100 and/or b) indulged too much in college!

- off road, I don't know yet. I have not been anywhere yet where the 100 could not do what was needed, but admittedly I have not taken it where there was a serious chance to damage it. But I have read several comments here by knowledgeable folks who swear that Trac Control is not as effective as Diff Locks. I believe them. And btw, YOU BETTER BE RIGHT CUZ THAT'S WHY I BOUGHT THE 80!!!!!!

Anyways, so I assume that for the real gnarly stuff the 80 should be better. For the light and medium stuff, the 100 is probably more comfortable and would do what's needed.
JMHO

oh, btw, guys, the other reason that I bought the 80 is that I can take it places without worrying too much about scratching it, unlike the 100. Of course, it would have been better to get a cosmetically challenged one rather than "PRISTINE2"...

, but eh, I like good stuff...
