If you can go for it, I would seriously consider looking at a 2000 Taurus, they are generally not that much more than a 1999, sometimes cheaper. 1997-1998 Ford seemed to be the best year for the Taurus. 1999, Ford deleted some things like rear disc, dual exhaust, etc. Engines available were the Duratec, Vulcan, and FFV (Fuel Flex Vulcan). The Duratec was the replacement for the Essex. You find this engine in all 1996-7 Ford Taurus LX's. The 1998 had the Duratec as an option on the base (LX) and the upper level (SE). 1999 it was only availble on the Taurus SE. The Vulcan was sort of the "base" engine, making 145hp. The Duratec is the more powerful engine, making around 200hp. Both of these engines are extermly reliable, and with basic maintence will last countless miles. Surprizingly, the Duratec makes similar gas millage to the Vulcan even though the Duratec is larger. I would defenatly recommend the Duratec if you want that extra oomph in power; the Vulcan does a fine job, but the Duratec just gives you more power.
If you are considering a 2000, I would defenatly look at the SES model. They have ABS, folding rear seats, power driver seat, all standard. Early in that 00 model year the line up was weird (in order) LX, SE, SE/SVG, SE Comfort. Later in the 00 model year it changed to LX, SE, SES, SEL. Duratec was available on the SE/SVG, and the SE Comfort early in 2000. Later in 2000 it was available on the SES and SEL. Duratec still had 200 horsepower, but the Vulcan in 2000 gained ~8 horsepower, giving around 152/3 horsepower. Also the 2000 and newer (known as Gen 4) transmissions seem to be more reliable than the 1996-1999 model years.
