I would really need to see the Service Schedule Manual that came with your car when new but 60Kmile service may mean New Fuel Filter (and an air filter) or even New Spark Plugs.

When was your coolant last changed and when was your accessory belt last changed? And even something like sunroof rail lube is important.

I'm sure you'll get a post from another owner just like you, but a MB Service Schedule Manual that comes with every new car is really a good guide.
