Thinking about a used Kia K4 in Ontario? This guide covers the 2025–2026 compact sedan — Kia's brand-new nameplate that replaced the Forte, and the model years Legacy can find. It explains how the K4 relates to the Forte, the trims, the engine, the drivetrain, winter notes and what to check on a car this new. Then it covers how Legacy finds the exact K4 you want and the two ways to finance it: an in-house lease, or a car loan through a lending partner (O.A.C.).
