Hi, I'm planning to buy a used 2004 Mazda 6 (4cyl). It has 71k miles on it. I'm not sure about the reliability of Mazda. Will this car give me a lot of problems and will it be high on maintenance? I've heard many people have a lot of problems with their Mazda 6's and 3's (especially those with the v6 engines). Should I give this car a shot or should I stick with looking for the Toyonda twins?
