Warning! I brought a 2009 Mazda 6 in for a pre-purchase inspection. I was told the car was in great shape other than needing an oil change. Less than two months later the front right side of the sub frame had been rusting away so long that it snapped. The sub frame snapped while my partner and I were driving, which could have resulted in serious injury. Although fortunately we were both alright. A new sub frame and labor cost between $2400-$3000.
