Sounds normal as the coolant temperature fluctuates esp. with different driving conditions, may be more fluctuations if it is in stop-and-go traffic. It tends to be more constant on freeway driving.
I mainly look at the engine oil temp in the SLK 55, as it needs to warm up to 80ºC before trying to go beyond 3000 rpm.
