Got stung with cartel on a clocked car before motor check showed it straight away!! But sadly that was after it was bought and tried to trade it a year later and the dealer told me the issues rang cartel and was basically told to F off its not their issue and still to this day that car shows no issues on cartel after I as the owner rang and reported it to them!!
Cartels wording of no issues found can also mean no history found hence they couldn't find any issues!!!
