Can you see where the coolant ends up on the ground? Front or side of engine or perhaps near the firewall? Radiator?

A good place to start is the coolant bypass valve as these commonly fail:

Hi Wulf thx for getting back, it was leaking near passenger side near brake fluid res but hard to tell the rac said looks like from water pump radiator seems fine no sign of leaks from coolent tank or anywhere that naked eye can see. But over last few days seems no leaks or loosing coolent how can it go from dumping lots out to none at all surely if water pump had gone it would still ne pissing out hmmm ant other ideas thx for ur advise

Sounds like the heater control valve to me. When they go they go big... and then often stop leaking for a while. It's right in the area you describe.

If you own some very basic tools and have ANY mechanical ability at all, you can do it yourself in your driveway in less than 1 hour. Otherwise I have no idea what parts/labor prices are like on your side of the pond. Here in the US I would expect to pay under $200 if using an aftermarket part, 250-300 for a genuine Saab part.
