Normal operating temperature?

[spinedoc]

Just had some overheating issues, replaced the thermostat and car is running within tolerance. But it seems to be running hotter than before this problem, only I never really paid attention to the guage before so it might be me being paranoid.

What is the normal operating temperature range for a SL500? Right now in stop and go traffic with 90 degree weather it goes up to 100 degrees celsius (the hash mark between 80 and 120), a hair over if I have the AC on. I seem to remember it would only go up to 90 or so before, but not sure. It sure is blowing a lot more heat out of the center console than it usually does, but it was a hot day yesterday.
