at 100kms, it should show even more actually tauri. the carproof/carfaxes are now showing services if they are done at registered places... so it should show a whole lot more than even 7. they do show a basic summary of what it was in for though as well, so if it shows "transmission, suspension, transmission, sunroof leak, transmission..." yeah... walk away... if it says service... cool. see how often they were doing it kms wise and backtrack...
