carsom and mytukar cars are also exposed to mileage rollback

They don't rollback themselves. But the previous owner/persons can always rollback before bringing it in to them. Their terms and conditions strictly says that they do not warrant for true mileage.

Carsome & mytukar depends a lot on the inspector individual itself. If the inspector is careful, they will have a lot in their report. If the inspector cincai, you also pening when you collect the car. A lot of times they didn't catch if the car was in a previous accident
