I currently own a Mazda 3. 2008. It's a really good car when it comes to performance and cornering. In terms of fuel economy, not much, the current model, I have 2.3 liters, consumes a lot of gas every time I drive it, forcing me to make more stops, so now I'm thinking about replacing the car with a mazda 6. Looked at mazda 6 review
and made sure that it has excellent characteristics.
But I will also say that maintenance is rarely required for the Mazda 3, it rides smoothly, with a little wear, but overall it is a pretty good car considering its age.
