Certified pre-owned.

The car has the remaining new car warranty and maintenance. It is CPO to 6yr-100k miles.
2006 2dr Convertible 215-horsepower 3.0L I6
6-speed manual RWD
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.

2003 2dr Convertible 184-horsepower 2.5L I6
5-speed manual RWD
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.

I experienced continued problems with the A/C system and the engine cooling system. Also, the rag top did not hold up well and developed a leak.
