not many people like the limitations of RWD in bad weather no one wants to be stuck at the side of the road.
Over 70% of Iconic5 sales are for the rear wheel drive car.
I think your sales figures are wrong, but regardless as I said not many people like to be stuck in almost 2 ton vehicle in bad weather just because of RWD, also in more normal conditions in the wet which we have a lot all RWD can be very skittish.
Then add in the professional reviewers stating the AWD is phenomenal compared to the RWD.
There is no point in us debating this. as its not meant to belittle the OP choice, but sadness that the AWD did not make the scheme in Ultimate trim.
