I think that already your header is wrong.
There is no car named Saab. But there is a SAAB. It is an abreviation of Svenska Aeroplan Aktie Bolaget (Swedish Aeroplane Company Limited).
The SAAB 93 went out of production around 1960. It was the 3 cyllinder successor to the SAAB 92 with a 2 cyllinder two stroke engine. And the SAAB 91... No, the SAAB 91 (or SAAB 91 Safir) is still around as a beautiful light aeroplane which was used for many years as basic trainer in the Flygvapnet - Swedish Air Force. Later came the SAAB 94 Sonett, a fine little sports car. And the SAAB 95 wagon version of the 93. All of them really smokey things until the 96 (a revised 93) arrived in the mid 60'es with a German made Ford four stroke engine).
Several years ago the SAAB small car division was sold to General Motors. New SAAB models are more or less luxury versions of Opel and Chevy cars, optimised for cold (Swedish) climate.
I'm pretty sure that you mix up the SAAB 93 (Saab 93) and the SAAB 9-3. That little difference represents a 40 years technology gap.
The 900 is a luxury Opel (Vauxhall) Vectra - don't remember the Chevy name.
In the homeland SAABs are generally considered ordinary cars of higher than average quality, but also more expensive. And official car inspection statistics tell that they get somewhat older than average before they are scrapped.
Maintenance costs: Hell, on any modern car, during the first ten years or 200 thousand miles you change oil, filters, tires, wipers, those brakes, spark plugs - and of course the cat. What else?
Ugly? Guess that some people think so. I think that they make beautiful cars. I only wish I could afford one, so I drive a VW instead, lacks luxury, but still somewhat durable.
