The 2009 Mercury Mariner offers some cool, cutting-edge technological features, but unfortunately most are available only as expensive options.
The Mercury Mariner is available in two trim levels, but Car and Driver contends there are "no meaningful differences between models." This isn't entirely true, however; Edmunds states that standard features on the base models include "full power accessories, air-conditioning, steering-wheel-mounted audio controls, a four-speaker CD stereo...and keyless entry," while the Mercury Mariner Premier models add "rear parking sensors, ambient interior lighting, leather/Alcantara upholstery, a power drive seat...[and] Sync." SYNC, which Edmunds says is "Ford's exclusive...multimedia integration system," wins high praise in reviews read by TheCarConnection.com, and Edmunds goes on to say that "the alluring Sync system gives [the 2009 Mercury Mariner] a technological edge over its compact SUV rivals."
SYNC is one of the many options available for the base Mercury Mariner; others include "dual-zone automatic climate control, heated seats, a moonroof, upgraded leather and a navigation system," according to Cars.com. For the Mercury Mariner Premier, Edmunds piles on more options, such as "17-inch wheels, step bars, a moonroof, [and] an upgraded seven-speaker stereo system." For those looking to bundle options, ConsumerGuide reports that the Mercury Mariner is available with an Amenities package that groups a "rear-obstacle-detection system [and] dual-zone automatic climate controls," while the Sun and Sync package for the 2009 Mercury Mariner base adds a "power sunroof, iPod adapter, wireless cell phone link, [and] voice recognition."
