I found an 06 Toyota Corolla that seems clean and checks out on the Carfax. However, if I were to believe the Carfax, the previous owner was neglectful with changing oil. Does the Carfax necessarily show all oil change records? What would a mechanic check for if the car was neglected?

Carfax Maintenance Records

If the previous owner was a DIY or had family or friends do off-the-record work on the car , it will not be in CarFax. My 79chev p/u & 92 Explorer are perfect examples of NO carfax records.
