Stay far away from any lease return/auctioned car which is what you're looking at. Most of those cars are very poorly maintained and you're likely to encounter future costly repairs even IF you have an extended warranty such as it being a "certified used car". AS time goes on and these extended warranty companies are facing increasing financial problems due to the high costs to keep these newer cars alive, more are denying claims and covering less and less as time goes on, not to mention a deductable amount each time.
The S60s havent been bad cars so far (compared to earlier S80s) but with more time and miles, who knows. 67K for a '01 car is alot of miles IMO too.
