It sounds like she would be going up to ski fairly regularly. If that’s the case then winter tires would be a great advantage. She doesn’t want to wreck that Audi. Have the chains available just in case.
I’m in the area. The mountains just got up to 3 feet of new snow in the past 24-36 hours. That’s typical. The snow just dumps sometimes. The passes will close for avalanche control or if conditions are too extreme.
She should also have in her car a bag with blankets, food stuff, etc in case she gets stuck for hours. That is a real possibility here.
