Saab quality has gone done related to the 2.3L engines. The pistons design has gone from a very robust unit to a more light wieght unit. The problem is that the light weight unit is then leaned out with the T7 and exhaust gas temps increased causing metal fatigue and piston failure. The fix is to reduce the egt's as much as possible and get a good air fuel ratio. What was also stated above only now applies to the 9-5 engines. The new 9-3ss, 9-2x are great cars.
