I went to Carvana to get some idea on what my car might be worth. I gave them the license plate, and it gave me a questionnaire about specific trim and options along with asking about the current mileage. I couldn't remember the exact figure so I guessed rounded to the thousand. The app complained and wouldn't take it as they knew the mileage which was some 150ish miles more. Apparently my car has reported the mileage last time I drive it, which has been about an hour before.

Carvana knew exactly how many miles I had driven within an hour of me driving my car.

So why did they have you fill in that field then?
