Normal operating temp.

I have same car and long ago questioned the temps.

What might be a source for a bit higher temp is the water pump. Some have different fin designs and cool at different efficiencies.

mine goes higher than 95C when driving up hill.

if it is not boiling coolant, and not in red zone, you are OK.

use appropriate motor oil and MBZ coolant.
