Now in it's final year of production, the 2000 Mercury Mystique is a compact sedan with seating for five. Two trim levels are offered; the GS and the LS. The GS is powered by a 2.0L four-cylinder engine which is paired with a five-speed manual transmission. This combination is good for well over 30 mpg on the highway. The LS trim features a 2.5L V6 which earns nearly 30 mpg on the highway and is available with either a five-speed manual or a four-speed automatic transmission.
