Cars

Hi
When some people sell cars some sell once they get to certain mileage even if they run fine why would that be
Would it be because they want something fresh and don't see point fixing big things when they go as they won't keep them long enough or like to sell while they're still worth money or is about that particular mileage usually when things start going and they don't want to fix them
Would it also be because the people that service then might tell owners they'll have to start spending money on them or sell while they are still good
Or maybe because there's nothing wrong and they just want something new
The ones that sell while still going once about a certain mileage before things go how do they know when they're going fine
