For least maintenance/issues:
Consider these:
Suzuki Swift DLX 1.3
Vitz (make sure to inspect thoroughly first)
Wagon R
Cultus 2017-18
The first two are automatics and I will only recommend auto, wagon r and cultus unfortunately are manuals.
Among Japanese I only included Vitz as we have a ton of them in Pakistan and parts are relatively easier to source. Avoid other JDMs if you can’t be bothered about parts and maintenance issues.
Excluded models older than 2012. For swift and Vitz in good condition you may have to stretch above 20.
