Mazda6 a reliable car?

[jrunknjrowzy]

Im looking to buy my first car soon, and I plan on buying a used Sedan. I've always liek how the Mazda6 looked and seeing as how its pretty big(Ima big guy) I was considering heavily especially afte seeing an 04 model with 46k miles on it for abotu 8 grand.
So I was wondering is the Mazda 6 a reliable car?
Hows the mileage?
Does it break down alot?
Is it comforable?
Is the insurance high?(Im 18)

Does it last long? (Im lookin to get at least a few more years out of it)

I prefer answers from peopel who have or do own this car, however any help is appreciated thanks.

I own a 2006 Mazda 6i Sports Sedan - very nice and it's got a smooth ride to it. I've owned my car for a year now - I bought it in last August. I really like it. Insurance payments depend mostly on the type of vehicle and age of driver/drivers. I have Geico - I pay 1--.00 a mine.
