As the other post asks, how long is a piece of string? You need toestablish what siezed, how badly damaged is it and what else is affected or not affected. Two scenarios and I don't know SAAB engines well enough to know if they both might apply. Basically, bearings seized as they stopped getting oil so the higher parts in the engine fail first.
1. The camshafts siezed, and the engine can no longer run without the valves going up and down. Problem with this is - what happened to the timing chain? Did it break, or just become dislodged. The crankshaft may still turn but bearings may be suspect. Also, may have damage to rings and pistons
2. The crankshaft siezed. All of above may also apply. Damage to crankshaft is probably severe - bearings rubbing on crankshaft journals do nasty things without oil.
So as first steo, I would take off valve cover, see if camshaft has any free play then make decisions from there. If camshaft moves then you almost certainly seized the crank and that's bad news. If camshaft seized, then crank may be OK and that may not be too bad a repair (new cam & cam bearings) but I would pull the crank and replcae bearings if no significant damage to crankshaft. The option of getting a replacemnet used engine is probably the best if you want to DIY.
