Certified pre-owned. |

It has a reputation with consumer organizations for very reliable performance - a real plus when repairs on such cars are so expensive. The "certified" warranty was important to me with this in mind. |

The car has the remaining new car warranty and maintenance. It is CPO to 6yr-100k miles. |

Parts(e.g., fuel pump) that would nearly outlast any domestic or foreign car make failed after only 25,000 miles. Dealer attempted to charge me nearly $2000 to replace same...said "No thanks," and took to independent garage who charged 1/3 to repair. |
