I love my S60, even with its flaws. In my opinion, the best looking body of any sports sedan. Great reliability history, especially for a Volvo. Let's hope they continue this trend. Ride is good. Peppy, but I'd prefer a bit more power. (I have 2.4T) Interior design is fine, but could be a bit more refined for a luxury sedan. (See Infiniti) Gas mileage is surprisingly good. An excellent used value, as Volvo's don't hold value like a BMW/Mercedes. Again, it's not perfect, but I love mine and doubt you'll do any better for the money in the used market.
Beautiful exterior design, safe and reliable.
A bit more attention to interior detail and Volvo really needs to pack more punch in their base models.
