Driving position & visibility
Tall or midget, fat or slim - will find an excellent driving position. Everything is within easy reach. Excellent heated outside mirrors, small(-ish) blind spots.
Controls and instruments
Very logical and minimalist approach, you only get what you need, no toys no trendy gizmos (iDrives, Navs, multi-color displays and touchscreens, etc.).
Powertrain performance
Explosive turbo performance, The car begs and provokes to drive energetically. Yet remains very stable and safe. ECM is made to digest any gas between Regular and Premium.
Front seat support & comfort
Multi-adjustable orthopaedic dream. 3 memory settings.
Rear seat room & comfort
3 adults can sustain rather long trips, even one in the middle gets decent seating position not requiring human origami.
Ride smoothness
While basic Arc suspension setup is excellent, Aero was made overly harsh and bumpy, to the point where it affect it stablility on grooved tracks. Soft tires are a must.
Feature availability
Depends on your point of view. If you like to count cup-holders and poke around touchscreens and multi-level menus - this is NOT the right car for you.
Reliability & durability
Dismal record up to 2000, at best unstable results to 2003, fixed all problems only by Model Year 2004.
Dealer practices
Very few around, parts prices are insane, be prepared to drive across half the country (in Canada) to find a truly qualified mechanic.
Past personal experience
One has to be VERY careful when shopping, the car requires constant learning and very educated approach, not suitable for an average A-to-B person.
Owning earlier model years (pre-2004) can make you allergic to any SAABs, not just 9-5s.
