The snow you see here is only 80 years old. The car showing was photographed during the Olympic Winter Games at Garmisch-Partenkirchen, Bavaria, Germany. No need to answer to this snowed in mystery.
It's just a heads up.
Perhaps this fresh winter snow will wake up your memory and help you producing good answers for the Xmas quiz starting on PreWarCar.com & PostWarClassic.com the day after Christmas. So Monday next.
In the meantime, Happy Holidays!
