I have owned my S60 since 2001, just hit 70k miles. It has been reliable and saved my life in a highway spinout at 70+mph. I have been lightly rear-ended twice and I felt nothing, barely any damage, this car holds up and I feel SAFE! It does well on gas mileage for long highway trips but is a total gas guzzler in the city. It performs well in winter weather. I change the oil every 3500 miles and keep up routine maintenance. Car is really spacious and the trunk holds a lot. Overall it has been a reliable, safe, easy-to-drive car and I receive many complement on its looks.
Seat warmers in winter! Smooth highway driving, little maintenance needed. Good turning radius, I park in a tight garage and it handles well turning corners.
Brake pad dust is excessive, especially on front wheels. Like others, my bulbs are always going out. I keep a bag of replacements in my trunk. Traction iffy in bad weather. Key fobs both stopped working at same time, reprogramming was very expensive!
