How Korea's Used Car Market Actually Works

Korea makes cars, exports cars and buys a lot of cars. What is less visible from outside is the second-hand machine underneath all that: a market of roughly 2.4 million transactions a year, historically run out of physical dealer complexes, now mostly run through three apps, and until very recently closed to the manufacturers themselves.

How big is the used market relative to new?

Volume has been flat to falling for years. Korean industry data shows the used market shrinking at a compound rate of about 0.7% a year from 2018 to 2024, with buyers aged 60 and over the only age group growing.

The export figure is the surprising one. Korea’s total automotive exports in the first eleven months of 2025 came to 66 billion dollars, up 2.0%. Strip used cars out and exports were down 4.2%. Used cars rose from 7.1% to 12.7% of the total, and carried the category on their own.

🚢 Korean used car exports, Jan–Nov 2025, by powertrain

Type	Units exported
Internal combustion	640,000
Hybrid	12,866
Electric	1,350

Leading destinations include Kyrgyzstan, Russia, Kazakhstan, Türkiye, Libya and the UAE, a map that follows sanctions patterns, road conditions and re-export routes as much as consumer preference.

Who actually sells the cars?

Three platforms and, since 2025, the manufacturers.

🚗 Korean used car platforms compared

Platform	Model	Purchase share (2022 survey)	Character
Encar (엔카)	Listing marketplace for dealers	60.7%	Largest inventory by far, recognition near 80%; buyer satisfaction relatively low at 36.6%
K Car (케이카)	Direct purchase and resale	16.7%	Highest satisfaction at 53.0%; own inspection and warranty; 12.8% effective market share in Q3 2025
KB Chachacha	Listing marketplace	10.8%	Bank-affiliated, financing integrated; over 80% of listings are private sellers
Heydealer	Reverse auction, dealers bid for your car	selling side	About 1.05 million app users; the app people use to sell rather than buy
Hyundai / Kia Certified	Manufacturer direct, inspected and warranted	expanding	Restricted until 2025, now unconstrained

The corporate histories are unusually eventful for what is, on the surface, a classified ads business. Encar began as an SK internal venture, was spun out, absorbed into SK C&C in 2013, then sold to Australia’s Carsales, which took 49.99% for 117.5 billion won in 2014 and bought the remaining 50.01% for 205 billion won in 2018. K Car was the SK direct-sales arm, sold to private equity firm Hahn & Company in 2018, listed on the main exchange in 2021, and agreed in April 2026 to a takeover by the KG Group, with a corporate renaming to KG Mobility Platform planned for August 2026 while keeping the K Car brand. Heydealer launched on Christmas Eve 2014 and added a car-buying service in 2024.

Why were carmakers locked out?

Because used car retail was treated as a protected small-business sector. Hyundai and Kia were barred from entering for years, and when they were finally admitted it was on a leash: Hyundai capped at 2.9% of the market from May 2023, rising to 4.1% from May 2024, and Kia at 2.1% then 2.9%. The caps expired on 1 May 2025.

The programmes are physically small relative to the market but growing. Hyundai’s certified centres hold around 538 vehicles at Yongin, 800 at Yangsan and 200 at Gunsan, and the retail operation launched in October 2024.

Why does everyone talk about fake listings?

Because the market earned its reputation, and then partly outgrew it.

The classic scheme is the 미끼매물 (mikki-maemul), the bait listing: a car advertised at an implausibly good price that turns out to be sold, damaged, or never to have existed, after which the customer is steered hard toward something else. In the physical dealer complexes, the equivalent was the 차잽이 (chajaebi), the tout who intercepted customers in the car park, a practice blamed in Seoul’s own account of the Janganpyeong market for driving away younger buyers.

Consumer redress filings specifically about used cars have run at a modest but rising level: 94 in 2021, 112 in 2022 and 124 in 2023, a three-year total of 330. Broader consumer counselling on used cars runs to around 10,900 cases a year and rises through the calendar, peaking in the fourth quarter.

How do you spot a flood car?

Flood damage is the recurring scandal after heavy summer rain, because water is easy to hide cosmetically and expensive to live with. Korean buyers check for it by hand as well as on paper.

None of this replaces the insurance record. It catches the cars whose damage was never claimed.

What does a car lose in value?

The government publishes residual value tables for tax purposes, which are not the same as market prices but are a reasonable anchor.

📉 Official residual value, non-commercial domestic passenger car (2025 notification)

Age	Residual value
1 year	72.5%
3 years	51.8%
5 years	36.8%

These figures are the basis for acquisition tax assessment rather than a forecast of resale price, so a popular model in demand will beat them and an unpopular one will not. As a rough Korean rule of thumb, about 20,000km a year is considered normal mileage, and over 200,000km total puts a car firmly in the old category.

Can a foreign resident buy a car here?

Yes, and the process is less exotic than people expect.

If you cannot read a Korean performance report and do not have a Korean friend who can, the certified manufacturer programmes are the pragmatic answer. They cost more than an equivalent car from a dealer lot, and what you are buying with the difference is not having to adjudicate a document you cannot read.

What happened to the dealer complexes?

They are still there and much diminished. Janganpyeong in eastern Seoul, which opened in January 1979, is the archetype: around 150 used car dealers inside a wider cluster of roughly 1,700 businesses covering 1,100 parts firms, 220 remanufacturers, 200 tuning shops and 50 repair workshops, employing some 5,400 people. Annual turnover across the cluster runs to roughly 1 trillion won in new parts, 100 billion won in used parts and 150 billion won in used car sales — note that the parts trade is now several times larger than the car trade it grew up around.

Its sales were already flat a decade ago at around 30,000 cars a year. Seoul’s plan for the site is to rebuild it as an automotive industrial complex with an integrated used car information system, a remanufacturing centre and an export support centre, which is a municipal way of saying that the car park model is finished.
