Bought my 2000 9-5 used in 12/03. Went with the manual tranny which made it a little sportier. Bad turbo lag, but once it is in the turbo, pretty quick. Handling is fairly tight, not sportscar tight, but pretty good. Overall I was happy with this car. It drove well with very few mechanical problems until just recently, then it seems like everything started to fall apart. I just sold it for a '99 M3 w/ 50k miles. I think I am going to notice worlds of difference.
Lots of standard features: in-dash cd/tape + changer in trunk, leather, dual climate, heated seats (front and rear), moonroof, 2 power points, Harmon Kardon factory sound, etc. If you want sporty, get a manual.
None. Appreciate it for what it is, a somewhat sporty sedan, not as sporty as the Germans, but you can get one with a lot of features for real cheap on the used market. I recommend getting one with less than 50k miles.
