How Hot is Too Hot?

[digieditny]

When I've been driving for a while the needle is between 80 and the next line (100?). Sometimes it gets close to the "100" mark (usually when I'm sitting at a light) but never passes it. If I turn on the heat full blast it goes down close to 80.

So I guess my question is.... Is hitting 100 too hot or is that within normal heat?
