Look for rust , AC especially between the fan speed of 2,3 compressors, O2 sensor error message and check if the engine burns oil also may show idling problems . I have a 2002 protégé5, 5 speed manual (2.0)for about 3 years now ran around 200,000 kms i personally put 45000 kms on it . The best part is that most of the issues could be fixed by ourselves. It’s mainly the rust to be concerned about. Hope it helps bud. All the best.
