Mazda really that good?

Hello, I have a question: I might want to buy a new car soon and maybe I would have thought of a Japanese…. In my relationship and family everyone is just so enthusiastic about the Japanese. Are they really so reliable? Or has that changed in the meantime? Do they have the latest technology like a BMW? And is the quality really so good? What about the lost driving? Or the fuel consumption? Is the Mazda 6 Sport Combi a reliable solid Car? Or is the Toyota Avensis better? Or are both bad? Thanks for your answers…
