Seeking advice

Hi there,
I got this 1990 Saab 9000s (190.000 km) recently. It seems it might have problems and I may be stuck with it. I need some advice.
I took the car to the Saab servcice. The guy told me "Knocking sounds could be heard from the engine. Could be piston slap (Pistons loose in cylinder) & Crank Bearings. Need to open the engine and inspect for precise evaluation." And he added "It's not worth it, it will cost you too much."
I took it to the guy who sold the car to me, to "try" returning the car and obviously he said something like "he used the money and cannot return it to me". The guy is a mechanic and a friend of a friend of mine. And he says if anything happens in three months he will fix it for me paying half the cost of the parts and all the labour (he'll fix it anyway). And he says that noise was there all the time when he was using the car too.
So obviously I cannot return the car, other than going to court and hope to get something like half of the money I paid. If I sell the car to scrap yard I'll just get %25 of what I paid. The best choice seems like continue using the car and hope it doesn't break, and if it does and if the cost is too much just sell to the scrap yard, or I try to sell it to another mechanic who is willing to fix the problem.
What to do oh what to do? Any advice is appreciated (I'm in Quebec/Canada by the way) - Deniz

Get a second opinion on the noise. I would bet (especially considering the model year) that it is a timing or balance chain / sprockets problem rather than loose pistons or rod bearings. When the chain is slapping around inside the timing cover it can sound like something else to the unitiated. This is not an expensive problem (yet) but could be if you let it go till the chain snaps or skips teeth.

It's not too difficult to find Saab engines around the Montreal/St. Bruno area. Depending on how much you have into the vehicle, and the condition of the car, it's often less expensive to swap the engine than to do a proper rebuild ( especially if the labour will be covered). Before you do anything, take Dave's advice and get a second opinion on the source of the noise ( look for an independant garage that specializes in Saab ), there is an excellent shop in Ottawa ( Scandinavian Auto Service ).
Good luck
