motors will last 250k+ w/ good maintenence keep up.

Whether the oil has been changed frequently is easy to spot, take the oil filler cap off and look for sludge on the rockers and the top of the head. If you see clean metal (may be stained brown, but should not have crusty sludge) it has been well maintained, or somebody cleaned it up.
