Friend is an engineer at the the plant, he had one for two weeks.
Fuel usage was 25lt/100... but he drove it damn hard.... like trying to break it hard.
Certainly they can have it inspected (at their cost)... I never said they could not.
However there is no searchable database a buyer can research to determine if there has been any prior accident damage........ Which part of this are you struggling with ?
I have several Thai friends who own/run secondhand car tents.... there is no system in place that can be referred to to establish damage history of vehicles here, unlike the USA which places damaged vehicles on a salvage title....... If they are paid out by the insurance company and then on sold.
Doubt there is any Thai insurers that would do it.
Its common amongst most Aus inurers though.
I only mention it as your post I qouted implies it is not a thing anywhere in the world.
