Mazda 6 has very good acceleration and gas economy. I like the way it looks, and it is very comfortable. There are two things I do not like about it. First, the windows rattle when they are down a bit. So you either have to put the windows all the way down or all the way shut. This is a very bad design because the rattling is annoying. The second thing I don't like it that I have received about four different recall notices on four different parts of the car. None of the parts are in the engine. They are mostly inside the cabin and the dealership takes care of exchanging the parts at no cost. But still this is a pain. But, overall, this is a good car.
