Buying a used car (GTFIH)

Was thinking of getting a new one but Cheapest new comes out to be 20k which is the Nissan Sentra or Mitsubishi Mirage maybe

Should I just buy a used one around $ 5-10k around 100k miles

Such as corolla civic yaris, Honda Fit

But I’m always worried it’ll always be in the mechanic shop needing repairs for that price
I don't check my CP, IDC about reps/negs
