A »When buying a used car, check if it's OBD-II compliant (most cars from 1996 onwards are). Look for the OBD-II port, usually under the steering column, and ensure it's functioning. A compliant vehicle with a working OBD-II system indicates a more modern and potentially less problematic engine. It's also a good sign for easier diagnostics and maintenance.
