We have a new e 350 4 matic with all season 17 in continentals. We had an Audi A6 Quattro that was great. I live in S.W. Pa, lots of hills, steep driveway, with one or two big snows mixed in every year. Will the 4 matic be ok in the snow or should I get winter tires right from the getgo? Did any of you have both cars? If so how do they compare? Thanks for any replies.
