The 1998 Mercury Mystique offer adequate headroom and legroom for adults to sit comfortably in the front seats. However, the rear seat lacks both headroom and legroom to accommodate anyone who is over 5’8? tall. The dashboard of the car has a modern design but retains its functionality, even though there are some poorly-placed stereo controls that are difficult to use. The trunk offers lots of cargo space, but the trunk opening itself is small, which limits the size of cargo that can fit into it. However, the cargo area is a bit wider at the rear, which balances out the whole situation. A 60/40-split rear seatback can be folded down for more space if needed. The top-end LS model of the 1998 Mercury Mystique has more interior features, including load on air-conditioning, moon roof, power locks and windows, anti-lock brakes, traction control, and a CD player with premium sound.
The 1998 Mercury Mystique base GS model has a two-liter Zetec four-cylinder engine with dual-overhead cams. This engine delivers 125 horsepower and 130 lb-ft of torque. The LS model is fitted with a 2.5-liter dual-overhead cam V-6 engine that delivers 170 horsepower and 165 lb-ft of torque. Both engines have a four-speed automatic or a five-speed manual gearbox. The performance of the 1998 Mercury Mystique can truly be compared to European sports sedans. Both models offer a well-balanced and competent ride even over the sharpest twists and turns. The best combination, of course, is the V-6 engine with the automatic transmission. The V-6 engine offers lots of power, while the transmission smoothly and crisply channels that power. Surprisingly, the automatic transmission works just as well with the four-cylinder engine. Although this engine is a little noisier than the V-6, it still offers a lively performance. Road noise is present for both models, but wind noise is low.
The 1998 Mercury Mystique has dual airbags, height-adjustable shoulder belts, and five-mph bumpers as standard. Traction control and anti-lock brakes are optional. The car received a full five-star rating for driver safety and four stars for passenger safety during frontal impact collision tests conducted by the NHTSA.
The 1998 Mercury Mystique's exterior has been restyled according to the recently modified Ford Mondeo that was launched in the European automotive market two years earlier.
