The SUV is really great, but I actually have a 2007 version of the Mariner. It was one of the first ones Mercury made, so I think for that reason, it doesn't get extremely great gas mileage. Probably 30 on the highway, and 32 in the city. Definitely better than most cars, but not nearly as good as some hybrids. But its a great shape and plenty of space. I really love it.
