is this car worth it?

hi everyone i’m a first time car buyer and i saw a 2017 audi a6 2.0t premium listed at 8k with 150k miles, is it worth it? further details on car include it had 2 previous owners. to note im a college commuter with a 1 hour drive to and from 3 times a week. is this type a car a gas waster or is it gas efficient? any thoughts and insights would be appreciated !!
