NPOCP: 91 Range Rover

This looks like a fun weekend off-roader. But when I read "Range Rover" I think time bomb. Warranted concern?

I don't know much about the aluminum block Rover engines. 173k could be just broken in or held together by it's own sludge. If it has good compression and doesn't smoke too badly, what else should I look for?

There's no air ride suspension or even electronic seat adjustments. No ABS either, so it seems like all of the good stuff about RR (off road ability) without all the useless electronic systems that can fail.

To borrow a phrase from jalopnik, would $800 be a "nice price or crack pipe?"
