I have almost 750 miles on my Crossfire and I don't have a problem with visibility when driving.
I adjust my side mirrors so that there is very little to no overlap with what I can see from the rear-view. Gives me good coverage on the move and practically no blind spots.
The convex passenger side mirror is sufficient to see the right side well IMO.
The only real visibility problem I have is when backing up, the tail is too high and I am still unable to judge where the car ends and short objects directly behind the car are invisible.
