To buy a coffee truck in Seoul, decide between a certified upfitter build and a vetted secondhand rig, then verify power, water, and zoning readiness before paying. New builds on Hyundai Porter or Kia Bongo platforms run ₩25–80M depending on espresso gear, battery/generator, wrap, and plumbing; used units list on Danggeun (Karrot), Joonggonara, Bunjang, and Naver Café groups for ₩15–45M—always demand maintenance logs and load-test the electrical. Target a 2‑group 220V machine (3–4 kW), 5–10 kWh LiFePO4 or <60 dB generator, 100–200 L fresh/grey tanks, inline filtration (TDS 70–120 ppm), winterized lines, and a POS that accepts ZeroPay/Naver Pay. Check your gu-office for designated food-truck zones and event permits; many operators book office parks (Gangnam, Yeouido), campuses (Sinchon/Hongdae), and film/K‑pop support gigs by contract rather than roaming. Choose suppliers in Guro, Bucheon, or Ilsan with KC-certified electrical and fire suppression; insist on a 1‑year workmanship warranty and weight sheet under the 1‑ton rating. Plan a menu priced ₩3,500–₩5,000, source beans from local roasters, and schedule morning commuter windows (7–10 a.m.). Budget insurance, commissary parking, monthly maintenance, and branded Instagram/Kakao booking. Pro tip: quiet power and clean water taste sellouts faster than fancy wraps. Location, power, and reliability drive daily revenue.
