Introduced in 2005, the Montego by Mercury was a full-sized family sedan that was built on the S80 Volvo chassis. It was offered in all-wheel-drive and front-wheel-drive, powered by a 3.0-liter V6 engine that was rated at 203 horsepower. A new aluminum trim, optional GPS system and rear DVD system, as well as updated audio controls, graced the 2006 Montego. Safety was the focus of the 2007 model, where seat-mounted side-impact airbags and side curtain airbags were made standard in addition to traction control. New options offered satellite radio and 18” alloy wheels. Mercury increased their drivetrain warranty to five years/60,000 miles for all models, too.
