I know you asked for C43 owners to help you decide, and I'm not one, however I can't resist any longer, the force ran out, and I found myself typing.
Throughout the process of selecting, buying, spec ing and waiting for your new car you seem to have been mithered at best, so I really don't think you will ever truly click with your new C43.
I think this issue will worry you whether your new car is affected or not. Perhaps this issue has given you an opportunity to get out. My advice would be:
10 X=ValuePreparedToLoseose
20 Y=ActualCostToCancelOrder
30 if y=0 then goto 100
40 if y<x then goto 100
50 if y>x then still f@c*ing goto 100
100 Cancel order
110 Enjoy your next car
