Just found a '95 Discovery - it doesn't appear to have any body damage that would have compromised the rolling chassis (slight rear end damage; probably didn't keep it from running at the time). It's at a friend's salvage yard and he's worried about the engine being bad (4.0 V-8).
Also, he doesn't know what parts may have been pulled, the interior is trashed with dashboard clearly cannibalized but no apparent engine bay parts gone. How hard are motors to come by or rebuild. Assuming it's free or near free (say, < $500) should I go for it or keep looking. It's an automatic but that's all I've ever seen.

What is the collective wisdom? Also, how much difference is there between the LR V-8 and the GM version?
