The Carbon Edition is less than $300 more than the Grand Touring Reserve, making it good value for money. Mazda’s 6 was already a good-looking vehicle, but the Carbon Edition highlights its beautiful lines even more in the model-specific Polymetal Gray Metallic paint. This color contrasts beautifully with the black 19-inch alloy wheels. The interior is spruced up thanks to red leather seats, a must on any performance car. These seats also have black cross stitching, while red stitching adorns the dashboard.
