1999 SAAB 9-3 SE review from UK and Ireland

Happily driving son back to university and car started making an awful sound from the engine I pulled over and as I did the car stopped. I turned engine over and noise was worse and car would not start up again. Got towed to my local garage and they informed me that my engine had siezed up. I needed to have a new engine. It has been very difficult to purchase a 2nd hand or reconditioned engine. Saab now have my car and are putting in the replacement engine. I have been in contact with Saab uk and the dealership where I bought my car from in 2006 they are not interested and are not admitting that there is a problem with these cars don't no where to go from here I feel they should bear the cost. I am very disapointed in saabs customer service or lack of it.
