Our Mazda CX9 has been with us for more almost 10 years, and it is still running extremely smoothly. We have driven it on many long road trips, and it has held up very well. We have not had any rattling sounds or excessive bumpiness when driving. We have 2 active kids, and the leather seats have not had a single scratch on them. The leather remains very smooth and soft. The engine runs extremely well even in cold weather. We have taken driven in snowy conditions, and we have always felt safe it in.
