On Monday the 24th, we had 12"+ of snow, wind blowing big time, and about 15 degrees. Windchill would have been much lower, and if on the road (not me!) white-outs would have compromised visibility for driving.
I've driven the Reatta in such conditions, and because of its low driver seat position, white-outs are quite scary. Much rather have the high seat position of my Avalanche. Since retirement, I now can "stay in" and wait for such conditions to subside before trekking out to shovel and use the snow-thrower.
