People who buy the CVT and don't maintain it or haven't got the money to fix problems when they go wrong don't like them.
To answer your questions:
I have a 350GT8 and have had it for 11months,
I drive freeway every day to work , on the freeway the RPMs sit at 2000 near the whole time , generally am either going 90kmp/h or 100-110km and it will comfortably sit at 2000rpms,
As you accelerate depending on how much you put ur foot down the car will pick rpms and sit there till you back off once reaching the desired speeds , generally when accelerating the car dosn't need to go past 3000rpms to reach speed quite quickly then drops back to >2000rpms
USING THE PADDLE SHIFTS IN THESE CARS ARE AMAZING. The shifts are near instantaneous and unlike other makes and models the car lets you drive it how you want without shifting itself whenever it feels like. It will only shift itself when it hits redline or drops below 1000rpms
I go on spirited drives quite regularly on some local VERY twisty mountain roads and the thing is amazing.
Also the power of the car is quite good. Have left many V8 owners scratching heads and car is quite capable to beat many cars , left my mates 260rs Stagea far behind, as few other models
