Looking a purchasing used, and I would rather not have a Project RZR.

Say on either a 800 or 570 how many hours is considered a lot? I realize how and where it was used and maintained is important. Its a water liquid cooled engine but if the oil and filter changes were done on time, how many hours before it due for some engine work?

Same on the transmission and differential? Am I looking at major work after say maybe 500 hours? Even if the off road was limited to just grass and dirt.
