I'd find yourself an independent Saab mechanic if you can. Have them check it out. Usually you'd be able to see an external leak of you would have oil in the antifreeze (black globs) or antifreeze in the oil (white mayonnaise like stuff). It that's not happening, the next thing to consider would be a leak in the turbo since the coolant would be vaporized and would just vanish. I'm assuming that someone has looked over all the hoses and clamps closely already. I've never heard of a "frost" (freeze) plug leak in a Saab. Bob
