You want to avoid 91 to 93? Sx1 because they have throttle body injection. Any Sx1 from 94 on (I don't know the year for sure) would be your best bet.
I have owned 3 saturns I love them because you can buy them cheap and they get decent mpg. I have had problems with the exhaust heat shields coming loose and making annoying rattle sounds on 2 of the cars. There is slightly better handling on the Sx2 because of wider tires and the rear sway bar. Also, a noticeable acceleration increase on the twin cam because of the hp and gearing (both bad for mpg).
2008 EPA adjusted:
Distance traveled by bicycle in 2007= 1,830ish miles
Average commute speed=25mph (yes, that's in a car)
My first car was an SW2 ('93 DOHC). I loved it. We threw all sorts of bad karma, crap etc. at it - and it just wouldn't die.
Really? My brother had a '96 SL1 and it was toast at 85k. A lot of it started when the radio got stolen (somehow this messed up a whole lot of electronics), but the motor started going downhill and the repairs totalled it out. Needless to say, we're not too hot on Saturns anymore. Always got great gas mileage though.
