Should You Buy the 2010 Mazda CX-9?

The 2010 Mazda CX-9 offers a compelling blend of family utility and enjoyable driving dynamics, making it an attractive used crossover. However, buyers must be acutely aware of two significant and potentially costly mechanical weaknesses: the VVT system and the automatic transmission, which can turn a great value into a financial headache if neglected or if prior maintenance was poor. With diligent pre-purchase inspection and a robust maintenance plan, it can still be a rewarding choice.
