Our 2010 3 Touring needed only a battery and a set of front brake pads in the 76,000 miles we put on before it was totaled in an accident. Our new 2014 3 Touring has 22,000 now and has never been back to the dealer for anything. I would have no problem expecting a Mazda 3 to reach 250,000 miles or beyond. They are extremely well made cars and even the corrosion resistance has improved in recent years. Zoom-zoom!
