Looking into buying a 1998 G320L with 50,000 miles on it.

The truck looks, feels and drives perfectly.

What should I look for at the engine bay and elsewhere that is not obvious to the eye??? I know what to look for on used S and E classes, but I am at home base with the G-class.

Any advise would be appreciated.
