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.

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.
