Mariner gets great gas mileage on average 24.5. Ride is comfortable but a little noisy from outside air. Plenty of interior room as long as you only are carrying 4. Plenty of cargo room for groceries but not good if you need to hall much more unless you fold down rear seat which is cumbersome. You have to take the head rests off to fold it down. I am a do it yourself er and can be inconvenient. Only mechanical problem has been a vibration in the accelerator pedal between 3 & 4 gear but is occasional. I noticed the same problem on a loaner car while in shop for problem. I figured it is just something I will have to get used to unless the transmission starts to slip.
I decided I needed to move from a sports car to an SUV and have always been a Ford girl. While doing some research I happened upon the 4 wheel drive Mercury Mariner. I am so happy with it! It is comfortable, roomy, versatile and has a ton of options! I am so addicted to the SYNC system and love the fact that my family can watch movies while we're traveling. The engine with its 6 speed transmission has some great power and I'm never left behind in traffic. The fact that I can easily tow our hunting trailer and carry the kayak on the roof was a major selling feature. I am thrilled!
