I recently purchased a used 2001 S80T6 and have been nothing but pleased with the car. My only complaints are that it could benefit from AWD and a 5 or 6 speed transmission. The manumatic transmission it has is still good and fun to use though. It has been well maintained and only accumulated an average of 9k miles per year. I previously owned a 98' S70 T5 and that car was enough for me to trust the reliability and quality that Volvo provides, the S70 has over 200k miles and still going! All it takes is following Volvo's regularly scheduled maintenance.
