Steve, I have a very similar car (late '93 900S Conv) and my temperature gauge behaves almost exactly in the way you describe. Or at least it does in hot weather, which I imagine you experience quite a lot of where you are. We moved here to Cape Town from London in September, and the car runs noticeably hotter here when the temperature's pushing 40 degrees than it ever did in the comparatively mild English summer. Bottom line? Your mechanic may well have been mistaken. As long as your cooling fan is cutting in - and, more importantly, cutting out again, then your cooling system is probably fine. The thermostat may be slightly ageing, or may have been replaced by an aftermarket part - in both cases this might cause the temperature to fluctuate slightly more than normal. For peace of mind you could replace the thermostat with a genuine Saab part. There are two types that open at 82 or 89 degrees; if you don't have it already you could fit the 82 degree one and see if it makes a difference.
