I was familiar with the bad rap the early S80's received and bought a 2002 anyway for my wife. It was under warranty and I figured the bugs should be worked out by now. So far the car has been wonderful to drive and own. We've had zero problems and my wife absolutely loves it. The 2.9 NA motor has decent power but is by no means a hot rod. Fuel economy is superb for such a large car and it is extremely smooth and quiet.
Styling (inside and out), fuel economy, safety features/ratings, comfort
I hate the electronic throttle... it's very hard to accelerate smoothly. Brakes, though excellent, are grabby and hard to modulate. A deeper trunk would be nice (baby stroller barely fits).
