We've owned our Volvo C70 for 18 months and so far no problems. Quality, build and fit is excellent. Car rides a little harsh but that is due to the 18" performance tires which wear out rather quickly ($300 a pop to replace). We get a lot of positive comments on the sharp looks. Have one major gripe. That is, the navigation system is a real "Dinosaur" to operate. The Japanese beat the Swedes in the electronic software department, again.
The DynAudio stereo is great! Even with the top down you can hear and enjoy the music. With the top up the car is very quiet and the stereo sounds even better.
Scrap the present Navigation system on next model upgrade. It's a shame such an archaic Navigation is installed on a car in this price range.
