Maintenance dillema
my father owned a Mercedes Benz S350 TD W140 1993. He died in 2012. and since then i drove the car, maybe, 10 - 15 times, that could be 2.000 kilometers (1.250 miles) maximum, for this six years.
The last maintenance was three years ago, when i changed oil, oil filter, fuel filter, interior cabin and air filter.
Can someone tell me what to do in these cases when the car is driven periodically and poorly - when i should do next maintenance, when to change oil, what to do with automatic transmission fluid, when to change belts and some more important parts?
I hope that someone can give me advice.
Thanks in advance
