Volvo V40D or Saab 9-3 2.2 TID

I have a Volvo V40 D , EZ 10/2004 with 116 Ps and 167,000 Km. Interested however for a Saab 9-3 2.2 tid .Bin with the Volvo actually satisfied , have it since June 2009 (ca. 1000000 Km ) no repair etc. Motor-wise it is also quite good but since I am interested for a Saab 9-3 2.2 tid I have concerns about the then expensive repairs that I do not know so eigenlich. With us near also no Saabwerkstatt and yet I would like such a car. a Saab 9-3 2.2 TID Linear EZ 08/2003 with 153000 Km , complete check booklet file at SAAB-SERVICE , thought . What about it ? Go this step or rather stay with the V40? As I said it is only about the risk with constantly occurring repairs (I like the car very well) what you read here some times or do I just see it too black?
