I owned a couple of VW Things (other aircooled too) and for a 2WD they do VERY WELL in the slick stuff. That Thing was a beast in the Snow being rear engined and rear wheel drive. Little under steer in the turns, but it went everywhere. The Gas Espar Heater in the '73 was a little scary but man did it heat. The only VW I had with decent defroster.
