Car appreciation... the aesthetics, the engineering, etc

Many.

95 was an old dog by the time it finished. Curr have one of the last full aero 95 Dame Edna jobs, 265hp as standard but drinks like it. Overall very ergonomic, everything works.
Weaknesses are..
The 2.2tid is very very old, low power and low economy but easy to fix and taxi like in reliability.
The 1.9tid (fiat engine) is the best for economy and power in tye reap world. Has issues like any modern diesel, but if servicing kept up and egr kept clean they are good for well over 200k
2.0 and low pressure 2.3 turbos are saabs bread and butter, by mid 2000 they were a very well evolved motor. Only weakness is absolute requirement for regular good oil change and sump dropped evry 50-70k to be raked out, they sludge. And the ignition pack om top of engine, only get genuine saab or misfires will plague you.

Honestly th E 9-3 estate is barely any different space wise and a more modern car in evry way than the 9-5. We had the old 93(gm) with the 2.0 full aero with mods bringing it to 265hp also, was utterly reliable, very drivable workhorse that could do as much as 47mpg which you will not get out of any other saab petrol engine in any other body style.
