Porsche 944 or Saab 900 turbo16s

Hello, I am planning a new purchase and am looking for a nice youngtimer, which is also suitable for everyday use and can still keep up with the acceleration on the road and on the motorway. In search of it, I noticed the Porsche 944 and the Saab 900turbo16s, which I like both visually, from the performance and also from the interior equipment. However, I am not quite sure which of the two I finally decide for The Porsche is often described as extremely reliable and durable, but the reperatures should go into the money properly, even if you try to make as much as possible yourself, is that true? Are the parts really so expensive? The Saab should also be very reliable, but you can hardly find specimens with less than 150,000km. As for spare parts and reperatures, the Saab should not be cheap either. The technology at the Saab is also not anz so simple, just because of the idiosyncratic motor/gear unit, which is often called not exactly screw-friendly. What tips can you give me to make the decision easier?
