I have a New Plus 8 and the CC works, but only over 60 km/hour. In Sweden one generally needs it for 30 and 50 km speed limits...
On the other hand, the speedometer seems to show 10 km/hour too much when one drives faster than 80 km/h.
I agree with Rob that the car works well in mechanical aspects, having just driven Gothenburg-Milan and back with not much issues. Did anybody mention speeding offences? :-)
