I purchased a certified used S60 from the dealer and have enjoyed the car from the beginning. It is slightly under powered but pick up is adequate and gas mileage is excellent- averaging 28 mpg to date. Interior is nice with the exception of the cheap plastic door handles. They squeak when your knee even brushes up against them. Stereo is great- especially with the controls on the steering wheel. My only real problem so far is with the bulbs on the car. I've had to replace two rear bulbs and to front lamps in 6 months. I had the daytime running lights turned off and hopefully that will help. With the warranty though, I haven't paid a dime.

See above. Transmission slips occasionally. I wouldn't buy one without the certified pre-owned 6-yr, 100k warranty. Overall, I really have enjoyed the car and would buy it again.
