While driving I noticed the temp guage, bouncing from low to mid guage. yes bouncing, not staying constant at all. it went down when accelerating, and up when stopped. Any clues?

Replace the thermostat making sure it is the genuine SAAB from the dealer! You don't have to drain the coolant, although you will lose some from the thermostat housing....just refill to required level after replacement.

Sounds more like a loose connection to me. The gauge seems to be reading either the correct temperature or nothing.

that sounds similar to the problems I had last week, replacing the thermostat cured it. Mine almost overheated when it was given a bit of stick.

Yes, but he says the gauge is going from zero to mid range (normal), not going into the hot range. If the gauge is bouncing I would think it's reacting too quickly for the problem to be heat / thermostat related. Could be a broken gauge though, but I would check the connections first, then the sender and gauge.
