If you run a search, you will find that these cars run pretty hot. Yes its very alarming to see the temp between the hash mark you described.
Let me do a search...and tell u whats up. I clearly remember a post regarding the AC and auxilary fan.
From what I've seen on my car....its pretty stays @ 80 or just above as I drive with the A/C...but when I stop the temp rises above the hash after 80..actually mid way to 120.
Then I went for a 20mins run with full A/C running @ 75mph with a ambient temp of 72.
Then I drove home....opened the hood....only 1 fan was on but the temp was still the same.
Let the car sit for another 20mins...same thing. The temp never went any higher.
