I buy a lot of beer token bikes and cars. Service history is good if it shows a timing belt change and any other known necessities for the model at that mileage.
120k plus cars are usually in line for major suspension parts, possible engine issues depending on models, but I hear Saab quality control was pretty good so not much to worry about other than the usual mechanical wear.
If nothing else, another car to strike off the list once owned. We all should have a Saab or a Volvo or two in our list.
