I'm moving to lake Tahoe. I have an Audi A6 with AWD, should i get a new car?

The question pretty much explains it.

I have an 01' Audi A6 with AWD. I've driven it up to Tahoe in the Winter, but they usually do a good job of keeping the roads clear. So I've never lived with it in snow, or in snow ever at all.

I can't afford much, but I'm thinking I might need a new car since I am moving there this month and will be living there all throughout winter as well.
Should I ? Or should I just get some good snow tires?

Thanks!

i think that a6 awd is good enough on snow with all season tires but its mpg is bad
