You guys are close on your taurus info, AFAIK
the progression is SE, SES then SEL
the SES has the option of the Duratech 200 horsepower engine, the SEL comes stock with the duratech. To my knowledge there is no Taurus LX, though there is a emmisions-package FFV engine with 105 horsepower (or there-abouts)
Don't let me fool you though, the taurus is really nothing to be afraid of, top end they are sluggish and low-end dont really have enough torque to get it done. After long trips in a taurus you end up with a "Sore ***" not a Tore ***
They're no slouch, but if you get traction you should walk all over them...
(my beater is a taurus, 155 horsepower model)
Watch out for my beast though
this POS Ford Rustang will walk all over most bonnevilles I'll see on the road
