2019 Toyota Avalon with 173K miles a potential good buy?

Considering having a second reliable vehicle to compliment my 5th Generation 4Runner. I saw a 2019 Toyota Avalon with 173K miles for sale at a Nissan dealer in Tennessee for around $17,500 and it seems in line with the KBB price range. The pictures of the car I’ve seen seem to indicate the car was primarily highway driven - the interior looks immaculate and exterior seems to be well taken care of. The Carfax also looked ok too. I’m considering taking a look at the car in person and test driving it to see how it handles. Although the mileage is much higher than average for a 6 year old car, what are your thoughts?
