K Car operates a direct-purchase used-car distribution model, buying vehicles outright, inspecting and refurbishing them, then selling them through an integrated Online-merged-Offline (OMO) network of nationwide dealerships and online channels.
Its core business lines include retail sales (B2C), dealer-facing auctions of purchased vehicles (B2B), the extended warranty program K Car Warranty (KW), and the vehicle-management platform MyCar.
In 2026 the company launched a new consumer-to-consumer (C2C) brokerage service, an asset-light business that earns brokerage fees without direct vehicle purchases.
The B2B auction segment leverages trust in K Car's own inspected inventory to achieve one of the highest bid-success rates in the industry, supporting faster inventory turnover and cash flow.
Competition comes from certified used-car programs run by Hyundai and Kia, online brokerage platforms such as Encar, and regional dealer networks, though K Car remains the dominant player among corporate direct operators.
A long-term tie-up with K Car Capital means roughly 90% of customers use in-house financing for installment purchases, adding another layer to the revenue structure.
In April 2026 a consortium of KG Steel and Cactus Private Equity signed an agreement to acquire a 72.19% stake, making KG Group the controlling shareholder; the company is in the process of changing its corporate name to KG Mobility Platform while retaining the consumer-facing K Car brand.
KG Group envisions an integrated mobility structure linking vehicle manufacturing (KG Mobility), used-car distribution (K Car), and IT platform services (KG ICT).
