The Mystique was only sold as a 4 door sedan. It was a front wheel drive car with a I4 engine standard and a V6 optional. Transmission options included a 4 speed automatic and 5 speed manual.
The V6 engine had some reliability issues, but when paired to the 5 speed manual transmission it was a surprisingly quick car.
One problem that owners had with this car was rear legroom. It would have been hard to design a car the size of the Mystique and provide less legroom. Even much smaller cars like the Honda Civic offered more legroom than the Mystique. Most customers at a Mercury dealership were willing to pay a little more for the Sable, which offered much more room and better interior features. In a fair world, the Mystique designers would have been fired and the Sable designers would have absorbed their salaries in addition to their own.
Car and Driver named this car to their annual Ten Best list in 1995, 1996, and 1997. It should be noted that all Car and Driver rear seat testers are double leg amputees.
These cars are easy to find on the used car market. They sell for about 1/6th of their new price, and sometimes much less. I've found them on eBay for a couple thousand dollars or less.
