The only reason I say a screen is that cars with a screen always have GPS connectivity. So either you buy a base model early 2010s car without it, or you get something older. Because then, it you're truly concerned about being tracked you can leave your phone at home. Plus, no Internet or satellite connectivity means it can't be remotely shut down. Of course, you'd want to buy it cash so the dealership or finance company aren't tracking you for repossession purposes.
