#1: I don't believe the temp gauge is really precise. As long as mine reads somewhere in between 85 and 105 C I do not worry about it.

A properly operating thermostat will keep the operating temperature relatively steady. I've had many cars, any many Mercedes and when you see the temp gauge moving around under normal operating conditions something isn't right. The only time the temperature should fall below normal is if you happen to switch the heat on while the car is at or near idle...otherwise it really should operate within a couple of degrees of the design temp.
The MB stat I removed would spike over 100C and drop to under 80 during routine running...that's just wrong. The new Wahler behaves normally, the car warms up and the temp stays steady. These gauges are pretty accurate if they're working right, and this one is.
A car which runs at 90C+ is above its design temp. When new, these cars ran at just above 80C...a car running at 95C-105C means either the gauge is wrong or the engine is running warm. 80-85C is not cool...it's normal for these.
