We have 16 plate XF’s and 18 plate CF’s.
The CF’s are the facelifted versions and seem fine. Yet the old 16 plate ones are absolutely terrible. One nearly stalled on me going up a 14 degree incline whilst fully loaded with 26IBCs. I have to end up driving the thing in manual just to get off the slip road at decent speed. They are bloody dangerous in my opinion. They used to be tanker units so I do not know if they are speced differently to normal units. (They have a different mid-lift and none of the aero).
