Yes but at some stage it needs a major service doesn't it?
I have never done a diff fluid change on it, neither spark plug leads, also quite possibly never a fuel filter.
When should these be changed?
And what else should be changed?
I have recently changed plugs, air/oil filters along with oil change each time, tranny flush, coolant flush, engine/transmission mounts, AC regass, and pressure switches for fan.
I don't think even the throttle body has ever been cleaned though. Intake runners/plenum must also be pretty dirty. Do catalytic converters or mufflers need replacing?

The car runs really well but just doesn't seem to be "like new". I have a feeling there is one or a few minor things with it which need replacing but I cannot tell which
