The reason factory doors are yellowish or ivory on the inside is that during the pre-treatment process in manufacturing new cars, the body is submerged in chemicals, but for vehicles that have had an exchange, that process doesn't occur, resulting in a gray color.

When opening the door and removing the rubber, if there is no circular groove or evidence of surface grinding, it should be assumed that there is a possibility of an accident or an exchange history.

On the 4th, at the Encar diagnostic center in Suwon, Gyeonggi Province, new employees of the used car sales platform Encar were receiving training from experts on the detailed inspection process of used cars to properly prepare used car performance and condition inspection reports.

The new employees closely examined the hood, doors, and trunk of the Sorento and SM6 vehicles to find any history of accidents, exchanges, or repairs.

The training course introduced methods that general consumers can also verify. For bolts inside the hood, the original has uniform paint, but cars with an exchange history show scratches. The silicone in various parts of the body is ripple-patterned on new cars, but after an exchange, if someone works on it, the pattern becomes irregular, and there are raised spots.

The performance and condition inspection report is a document that used car sellers must inform consumers about according to the Automobile Management Act. Encar introduced used car diagnostic services in the early 2000s, before the performance inspection report became mandatory.

Located next to the Suwon used car market, which holds a Guinness World Record with more than 12,000 used cars, the Encar diagnostic center verifies the accident history, options, and vehicle grade. Artificial intelligence (AI) photo analysis technology also assists in the expert review process.

After taking pictures and pricing the vehicle, it is registered on the platform. Vehicles validated at Encar diagnostic centers nationwide account for about 400,000 annually, representing approximately 70% of the listings on the Encar platform.

One employee who participated in the training noted, 'This has alleviated the vague sense of distance and anxiety regarding the used car market, and has become an opportunity to gain confidence in practical work.'
